knee mystery!! i am a 16 year old male with a history of growth related knee pain: osgood-schlatters and patellofemoral syndrome. thankfully, those ailments have subsided for now, but as of recently, i have another knee ailment that is probably the most painful yet. it is in my left knee on the inside (medial) --- this link has pictures of where it hurts exactly
i have seen two pt guys and one orthopedist, both of whom examined my knee and although did not directly conclude this, none thought i had a mcl or meniscus tear based on physical exam. i have not gone for an mri for lack of insurance coverage.
as far as biomechanics, both my hips are internally rotated, and i toe in while walking, running, biking, etc (although i believe toeing out is what causes medial pain). i also have extremely flat feet, but i wear supportive shoes and custom orthotics.
it first came while doing elliptical trainer--it was sharp, as if nails had been driven into it. it comes back when i walk too much, bike too much, or especially play any sports that requires pivoting on the knee (tennis, eg.). it does NOT hurt to run briefly or perform any squatting exercises (even with very heavy weight). it seems to hurt more with time used rather than the manner in which it was used, and it seems like if i can keep my knee directly in alignment, it hurts less (although it's quite hard to focus on that at all times).
i do notice it a bit in my right knee, but it is not really painful or in anyway debilitating (which leads me to believe that it is perhaps not an acute injury--i can recall no specific instance or trauma that may have caused this except. however, the onset was quite sudden on the elliptical). there will be days when i can bike for 20 minutes without any pain, but, occasionally, the next morning, it will hurt more.
i don't know what to do about this pain. i've had it since the middle of march (2010), and i know that my patellofemoral syndrome took about 9 mos. to calm down.
any suggestions? i've researched mcl sprain / meniscus tear online, and don't think i have either (although i may very well have one). there seems to be a dearth of any other diagnoses for medial knee pain, so i am desperate!! i just want to be pain free for the first time in years. i won't have many more years to play organized sport
