Hi,
thank you for providing the brief history of you,
As by reading your history, it is unfortunate to see that no diagnosis seemed to come in hand and your symptoms are still persisting.
I can recommend you to under go
physical therapy. Did any one advised you in the past? if not then please go to the physical therapist, as it is non invasive, no side effects and most cases with unknown diagnosis and cause can be helped.
In my clinical practice patients walks down to me saying
knee pain, but apparently there is no actual diagnosis with them from ortho, so we look for muscular assessment and proceed to exercises for not only strengthening the knee, but also the core, pelivc foor, spine, hip and both lower
limbs. We are to rehabilitate the knee with different measures and an individual basis rather going conventional. We get almost 99% of success in reducing the symptoms and also good strength as well.
I will recommend you to consult a physical therapist. It will surely help you get rid of the pain and aches.
Regards
Jay Indravadan Patel
