Blood tests, bone scan, x-ray, MRI and nine (9) doctors do not know what it is. Predisone did not work. Ibuprofen and Tylenol worked for about a year- now it does not work. Just started Aleve; it works well. The pain is inside one knee. On a scale of 1-10, it gradually goes to a 7. Teenager. There is no history of any sports (except gym) or accidents. Tests show nothing.
There has been a scanogram, which showed a 1cm discrepency (1cm is in the normal range). The pain is in the center, inside the knee. The pain is not worst with any different position or movement, it is not worst in the morning or at night or anytime, there is pain all of the time, and it does not hinder any exercise (except is very difficult to preform any movement when in pain, like sitting straight). No mental problems (no depression, though it's wearing me out; during the points that I'm not on medicine, it gets to an indescribably amount of pain), and social/educational wise, I am an honors student who has close friends.
I've seen a regular doctor, a sports medicine doctor, four (4) reumotologist, an ostiopathic doctor, a neurologist, and an othopedic surgan.
Some theories (from doctors) include: hyperactive nerve, discrepency (ruled out), and refered pain to the knee from the hip (when you're under age nineteen [19] there's something with the brain not being fulling wired).
