My Fibular Head On The Right Leg Looks A Little

My fibular head on the right leg looks a little bit enlarged and some pain present when palpating a little bit harder around that area (difficult to sit in lotus position). I am not sure if that is because of the enlarged fibula head itself, or because of some type of injury. At the same time I have something that mostly looks like Osgood Shlatters disease, probably from my early childhood, and able to move most of the bones in my right knee, but it is not the same with left knee, which does not have these problems. Also, my knees often cracks, especially the right knee, when stretching at certain position (mostly early in the morning), and when climbing stairs. I know it is not easy to make a diagnosis this way, but what do you think about my situation?
I am in my 40-es and have genetic predispositions for joint problems.
Thank you in advance for your answer.
