What is rotator cuff muscle pain?

The rotator cuff muscle consists of four muscles that surround the shoulder blade.
When any muscle tendon is injured, inflamed & worn down, it is produce rotator cuff muscle pain.
You are seeing the swellings & spasms in the area of pain.
This pain is reduced by the RICE principle & physiotherapy treatment.

What is the anatomy of the rotator cuff muscle pain?

The rotator cuff is made up of the muscles & tendons which are located in the ball means the head of the upper-arm bone = is the humerus In the shoulder joint socket.
This rotator cuff muscle helps you raise & rotate the arm.

The rotator cuff muscle includes 4 muscles:

Supraspinatus muscle = This muscle holds the humerus bone in place & keeps the upper arm stable & helps to lift the arm.
Infraspinatus muscle= This muscle is the main muscle that is led to rotate & extend the shoulder joint.
Teres Minor muscle = This muscle is the smallest rotator cuff muscle, the main job of this muscle is to assist with the rotation of the arm away from the body.
Subscapularis muscle= This muscle is holding to upper arm bone to the shoulder blade & helps to rotate the arm, hold the arm straight out & lower to arm.

What is the cause of the rotator cuff muscle pain?

Rotator Cuff Tendinitis:
This Rotator cuff tendinitis is most common in young athletes & middle-aged adults.
This tendinitis occurs when the normal & healthy rotator cuff tendon becomes injured & inflamed.
Some Sports & activities that require a lot of throwing & overhead arm motion which is become to cause the tendinitis like as swimming, tennis, volleyball, baseball & weightlifting.
Certain chronic diseases which are also associated with rotator cuff tendinitis such as diabetes & obesity which are become risk factors for muscle pain.

Rotator Cuff Tear:
A rotator cuff tear occurs when the muscle-tendon is torn from the arm bone.
This Rotator Cuff tear is found mainly in middle-aged & older adults.
This Rotator Cuff tear is caused by trauma like a fall directly on the shoulder joint & direct blow to the shoulder. when the do the Chronic overuse of the rotator cuff muscles which is also contributing to this muscle tear.
Obesity & smoking also increases a person’s chance of tearing the Rotator Cuff

Rotator Cuff Tendinosis:
Rotator cuff tendinosis which is a condition in the tendons starts to weaken & thin out due to ageing.
In this Tendinosis decrease in blood supply to the rotator cuff tendons.
when the tendons become too stressed & injured, it is not recovered & heal as well.
Poor posture, repetitive overhead activity, smoking & genes also play a role in the development of the rotator cuff tendinosis.

Rotator cuff pain is also due to playing sports that involve throwing & overhead reaching, like baseball & swimming.
Other causes of muscle pain include ageing & weakening of the tendons or injuries of the shoulder.

What are the symptoms of the Rotator Cuff muscle injury?

You feel Sharp & aching pain in the area of pain.
Swelling is also present located over the front or outside means the lateral part of the shoulder joint & upper arm.
In some cases, you feel the pain farther down the arm.
You feel the difficulty performing activities like combing the hair & reaching behind the back.
Loss of strength in the arm means you notice to have a hard time putting dishes away in the upper cabinets & reaching into the refrigerator to lift a carton of milk.
You also feel Pain in sleeping on the affected shoulder joint.
The feeling of Throbbing pain at night is also common with the rotator cuff tendinitis & tear.
You feel the Swelling, redness, bruising & warmth around the shoulder joint.
Shoulder pain is along with trouble breathing, dizziness & abdominal pain.
You feel the Difficulty in lifting the arm above the head & carrying objects.

What is the Diagnosis of the Rotator Cuff muscle pain?

The doctor is taken down to medical history
Then perform a physical exam
The doctor also examined the range of motion & strength of the upper limb in the examination part of the assessment.

The doctor is do the Imaging scans, such as an X-ray or an arthrogram = which is a type of detailed X-ray which is help to identify any bone spurs.
These small bone growths are rubbed against the rotator cuff tendon which produces pain &inflammation.
MRI & ultrasound scans are also be used in the diagnosis.
These tools examine the soft tissues, including the tendons & muscles.
These tools help to identify tears & show how large & severe the tears have become.

Test for the diagnosis of the Rotator Cuff muscle injury:

When you feel a rotator cuff problem, the healthcare provider is advised to perform some tests to evaluate the rotator cuff tendons injury.

Empty Can Test:

This empty can test is help you check the supraspinatus, a muscle that is located on the upper part of the shoulder.
This test is a simple test to perform.

You are Sit or stand comfortably.
Lift the painful arm out to the side so the arm is parallel to the floor.
Bring the arm forward to about 30 to 45 degrees.
Turn the hand over so that thumb is pointing toward the floor.
Have the other person which is applied gently push the arm down.
When the produce pain & weakness prevents you from keeping the arm in the “empty can” position, it is indicated to supraspinatus rotator cuff injury.

Lift-Off Test:

This lift-off test is a shoulder test which is help to determine the tear in the subscapularis muscle.
This test is responsible for rotating the shoulder inward.

You are Standing up & place the back of the hand on the small of the back.
Face the palm away from the back.
Then Attempt to lift the hand away from the body.
If you are unable to lift the hand away from the low back, it is indicated to be a subscapularis rotator cuff injury.

Resistance Testing:

This test also helps to for determining the rotator cuff tear which also causes the shoulder pain for to perform the manual strength testing of the rotator cuff muscles.

You are sitting comfortably in a chair.
Bend the elbow joint at 90 degrees & must keep the elbow joint tucked into the side.
Have someone push the hand in toward the belly.
When you are unable to hold this position & produce pain, it is indicated to rotator cuff tear.

Pain-Relief Test:

This test is commonly performed by orthopedic surgeons & sports medicine specialists.
It helps to distinguish between pain that is caused by a rotator cuff tear & pain caused by tendonitis.

The doctor injects lidocaine, which is an anesthetic drug that does numb the area, into the shoulder joint.
When you are suffering from rotator cuff tendinitis, that lidocaine is relieve the pain & muscle strength is remain normal.
Because of this test, the pain will be relieved, but the muscle becomes too weak.

When the doctor found to large tear, the primary healthcare provider is referred to you the orthopedic surgeon.
Sometimes large tears of muscle are needed for surgery & repair to tear.

Differential Diagnoses of the rotator cuff muscle pain?

Not all rotator cuff muscle pain occurs from the injury area.
Doctors often want to rule out other possible causes for a person’s symptoms to help them make the right diagnosis so that need to differential diagnosis for rotator cuff injury.

Some other musculoskeletal conditions which also affect the muscles & bones which is also produced similar symptoms of rotator cuff muscle injury include:
Frozen shoulder
Osteoarthritis
Shoulder instability & dislocation
Labral tear
Biceps tendonitis

This Differential Diagnosis occurs with the imaging tests.
An X-ray is show signs of osteoarthritis.
An MRI is used to diagnose the labral tear.

What are the Risk Factors for rotator cuff muscle pain?

The following factors increase the risk of rotator cuff muscle injury which is lead to rotator cuff muscle pain :

Age:
When you are older, risk of the rotator cuff injury increases.
So that Rotator cuff muscle tears are most common in people who are older than 60.

Construction jobs :
Some Occupations like carpentry & house painting which is required repetitive arm motions in the work that applies to overhead on the muscle which is lead to damage to the rotator cuff muscle.

Family history :
Some genetic component is also involved with the rotator cuff injuries which appear to occur more commonly in certain families.

What are the complications of the rotator cuff injury?

The most common complication is that occur to re-tearing of the rotator cuff muscle after healing.
When does the surgical repair for the injury that may occur to the risk of the postoperative complications?
The General surgical risks include blood loss & issues with the anesthesia.

Some other complications include to :
Permanent stiffness
Frozen shoulder
Reduced cuff strength
Loss of motion

What is the treatment for the rotator cuff muscle pain?

RICE principle :

In the starting phase of pain reduction, muscle pain & swelling are applied to the RICE principle.

R – rest = When you feel the pain must be Avoiding to activities which are aggravating the pain, like overhead reaching & reaching behind the back means do the rest for someways.
I – ice = Applying ice on the area of pain for 20 minutes which is used to reduce pain & swellings, you can also apply an ice pack & frozen peas to the area of pain.
C- compression = Applied to compression bandage on the area of muscle pain for release to swelling by to compression but not use to slings because it is the risk for the frozen shoulder.
E- elevation = Elevate to affected arm for release to swellings with the help of a pillow.

Pain medication:

**treatment for the rotator cuff muscle pain**

You are taken to the over-the-counter drug for release to the area of pain.
In the over-the-counter drug, you are taken to the nonsteroidal anti-inflammatory drug (NSAID) like Advil (ibuprofen) drug.
You are also applied volini gel & diofance gel on the area of muscle pain for pain release.

Heat therapy:

You are also applied heat therapy to the area of muscle pain release to swellings & muscle pain.
You are applied to a hot pack or heating pad on the area of pain for 10 minutes & 3 times per day.

Surgery:

Sometimes surgery is necessary for this muscle pain.
When this injury occurs Young athletes often need surgery.

Rotator cuff muscle repair surgery is done as an open procedure & a minimally invasive arthroscopic one.
The surgeon is advised on which is the approach best for you.
This depends on the exact location of the rotator cuff damage & how severe to injury is.

What is Physiotherapy treatment for the rotator cuff muscle pain?

The physiotherapy treatment includes massage, electrotherapy, stretching & exercise, and strengthening exercise which help you release pain & swelling.

Massage:

Massage helps you release trigger points & tenderness of muscle pain.
It is also decreased muscle pain & swelling.
Massage is applied by a physiotherapist to the trigger points of the muscle for 5 to 10 minutes.
It is applied with the help of oil.
The therapist is also used to massage machine release to spasm of muscle.

Electrotherapy:

The electrotherapy includes SWD, TENS, IFT, US, and Deep heating therapy which is used to release the pain & swellings as well as spasms.

For release to tender points & swellings, the therapist advises to US = an ultrasound machine for 5 minutes with volini gel.
For release to pain as well as swellings physiotherapist advice to SWD = short wave diathermy, IFT = Inferential therapy & TENS = trans-cutaneous electrical nerve stimulation for 10 minutes.
So that electrotherapy treatment is required release to muscle pain.
