Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the pain in the right shoulder, right foot and right hip.
These joint pains seem unrelated to the accident injury sustained by you.
3 years back. You must consult your personal physician for the thorough work up to rule out causes of joint pain such as connective tissue diseases, arthritides etc. as the same is not possible online.
Hope this helps. Take care.
Note: This post is not to emphasise final diagnosis as the same cannot be made online and is aimed just to provide medical information and no treatment suggested above be taken without face to face consultation with health care professional.
