Well, without a clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities for the knee issues that may need to be considered include injuries to the internal knee structures loose bodies, degeneration etc.; while hip issues could be caused due to over-exertion, inappropriate warm up, neuro-muscular issues, injuries, inflammations etc. I would suggest getting these evaluated by an internist initially and depending on the cause diagnosed/ suspected, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.
