Hello,
Chronic pain in the right shoulder is something that needs attention. The causes may be
frozen shoulder as in diabetes, shoulder joint
osteoarthritis,
polymyalgia rheumatica, rotator cuff tendinopathy,
cervical radiculopathy or sub acromial bursitis. All these conditions require pain medication.
Percocet is a combination of oxycodone and
acetaminophen. It is a safe drug in relation with kidneys, meaning it doesn't have adverse effects on kidney. Percocet can be accustomed or the term used is tolerance. That's why your pain is not getting relieved as it was previously.
A few medications you can use but with caution are NSAIDs like Ibuprofen, Aceclofenac can be used twice daily for 10 days only and only if you don't have any kidney malfunction,
corticosteroids can be used when the pain is severe and Prednisolone 10mg daily once for 10 days then 5 mg for 5 days and then 2.5 mg alternate day for 5 days.
You can have a opioid alongside like Hydrocodone or Oxycodone.
Physical therapy would help a lot. After relief of acute pain, please go for physical therapy where you can learn some stretching and muscle strengthening exercises that would help in pain relief.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
