Bone & Muscle problems

Dear sir, I am 25 year old male suffering from knock knee. I just wanted to know that is it possible to correct knock knee by only exercise. Please guide me through this with genuine feedback.

I have been having sever pain in my back and have been facing stiff neck since 4 years. My mri reports are saying that my lumber spine is straightening and also mild circumferential disc bulge seen at L4/L5 and L5/S1 levels without significant neural encroachment. Straightning of lumber spine noted possibaly due to muscular spasm.

I had viral arthritis about 2 months back. Fever was only for 2 days. But all my joints like ankle, fingers, toes, wrists, shoulder, elbow and neck pains are still severe. Morning its more compared to later part of the day. I have consumed medicines and applied some massaging oils and creams. But no much relief. Please help.

3 Months back I was handling a bike but I forgot to put it on stand. The bike weight was full on my left hand. Some type of pain was there on my wrist. At that time as suggested by doctor i took an X-Ray but there was no problem in bones. But my Carpals and wrist bones were paining alot while carrying any weight. While rotating my wrist now sometimes a sound comes from it and can't even lift weight properly without support. Which doctor should i get treated from bone or physiotherapy.

I had a injury of finger wherein it was jabbed in motorcycle chain. Now the issue is tendon was not repaired at that time and it has been past 5 months now. My distal phalanx is not straight. What can be done now?
