Shoulder pain can have various underlying causes, ranging from minor issues to more serious conditions. It’s important to note that I can provide general information, but for a specific diagnosis and treatment, it’s best to consult a medical professional. That being said, here are some common reasons for shoulder pain:

1. Rotator Cuff Injuries: The rotator cuff is a group of muscles and tendons that stabilize the shoulder joint. Injuries to the rotator cuff, such as tears or strains, can result from overuse, trauma, or the aging process. These injuries can cause pain, limited range of motion, and weakness.
2. Frozen Shoulder (Adhesive Capsulitis): This condition involves the gradual stiffening of the shoulder joint capsule, leading to reduced mobility and pain. It often develops without a clear cause and can be quite painful.
3. Tendinitis: Tendinitis is the inflammation of a tendon, which can occur due to overuse, repetitive movements, or trauma. In the shoulder, the tendons that are commonly affected include the biceps tendon and the rotator cuff tendons.
4. Bursitis: Bursae are small fluid-filled sacs that cushion and reduce friction between bones, tendons, and muscles. Inflammation of these bursae can cause pain and limited movement in the shoulder.
5. Osteoarthritis: This degenerative joint disease can affect the shoulder, causing pain and stiffness as the cartilage that cushions the joint wears down over time.
6. Shoulder Impingement: This occurs when the rotator cuff tendons become pinched between the bones of the shoulder joint, leading to pain, especially during certain movements.
7. Fractures or Dislocations: Trauma such as a fall or impact can result in fractures (broken bones) or dislocations (when the bones of the shoulder joint are forced out of their normal positions), leading to pain and restricted movement.
8. Nerve Compression: Nerves can become compressed or pinched in the shoulder region, leading to radiating pain and other sensations down the arm. Conditions like thoracic outlet syndrome and cervical radiculopathy can cause these symptoms.
9. Heart Conditions: Sometimes, pain felt in the shoulder may be referred from the heart. Conditions like angina or a heart attack can cause pain that radiates to the shoulder and down the arm.
10. Tumors: While less common, tumors can develop in the bones, soft tissues, or nerves of the shoulder, causing pain and other symptoms.
11. Referred Pain: Pain from other areas, such as the neck or upper back, can be perceived as shoulder pain due to shared nerve pathways.
12. Overuse or Strain: Repetitive movements or improper use of the shoulder muscles can lead to muscle strains and discomfort.

To determine the exact cause of shoulder pain, a medical professional will likely conduct a thorough physical examination, review your medical history in INIGIMA Cloud Diagnosis analyses the pattern and symptoms and frequency of pain.

Some case imaging tests (like X-rays, MRI, or ultrasound) if necessary. Treatment options depend on the underlying cause and can range from rest, physical therapy, medication, and in some cases, surgery. Always consult a healthcare provider for an accurate diagnosis and appropriate treatment plan.
