Detailed Answer:
Hello,
Shoulder pain has the following causes :
1) cervical radiculopathy
2)cervical spondylitis
3) osteoarthritis
4) shoulder joint synovitis
5) rotator cuff tendinopathy
6) polymyositis
7) subacromial bursitis
8)frozen shoulder
9)periarthritis due to hypothyroidism
To those who come to my clinic with similar symptoms, i recommend the following :
1)Pain relieving medication like NSAIDs tab.ibuprofen or tab. Naproxen to be taken twice daily for 14 days.
2) To prevent gastric irritation, tab.pantop 40 mg to be taken once daily before food. You can continue Omeprazole or take pantop.
3) If you have kidney disease or bleeding disorders, NSAIDs are not to be used. Then you can use opioids like hydrocodone, oxycodone and Tramadol daily twice.
4) physical therapy to strengthen the shoulder muscles and reduce pain.
5) You need to have an x ray shoulder to rule out fracture.
6)you have to check thyroid function tests and if the dose of thyroid medication is adequate. If it's inadequate, you may need to increase the dose.
If your pain doesn't subside even after 14 days of above treatment, you may consult an orthopedic specialist for further evaluation.
Hope i have answered your question.please let me know if you need any further assistance.
Thank you. Take care.
