I may be wrong but you probably have osteo arthritis like me in my right knee. I have seen a few different specialists about it and had most of the cures from Mobic pills to injections. I have seen several ortho surgeons and it's just a merry go round of advice. You could probably find the best advice online as, short of a knee replacement, you will go through lots of appointments and lots of meds. What age are you and had you had any previous damage to the knee? Over the course of 45 years I had 3 arthroscopic operations on my knee and it is now nearly bone on bone in the joint. I'm 70 and am not interested in a huge operation and rehab period getting a new knee so I am managing it with Tiger Balm, exercise and pain killers.
