I have read your problem.
Sore joints may be due to arthritis, gout
, rheumatoid arthritis
, some infection of joint, inflammation of a bursa etc.
You may have to go to hospital for your further management.
There your doctor will do your physical examination, and some blood tests e.g serum uric acid, serum RA factor, ESR
, CRP etc.
Your doctor may also prescribe you x-ray of joints involved.
Send us all the reports of above mentioned test or discuss it with your doctor.
After knowing blood tests, x-rays reports and physical examination, only then your diagnosis would be made and further treatment is advised.
Do not take painkillers/ muscle relaxants without prescription of doctor they may cause you more harm than benefit.
I hope you have get your answer. You are welcome to ask further health queries.
