Ilene - a belated thanks for your input
I have an online friend who is a registered nurse, I described my symptoms to him and this is what he told me...
"This is what I hear...Not lateral pain. Not medial pain. no locking of knee..Rules out meniscus. No history of acute trauma, therefore not likely collateral ligament injury...Possible patella bursitis. If so, the naproxen will make a big diffrence in 3-5 days...Other possibilities left are a cruciate ligament tear. Possible from your aerobics, but not usual without acute injury. the cruciates don't gradually become problematic.. For awhile you were descibing a bakers cyst, but not likely. Not much left to figure out without a hands on eval....Therefore, be really deligent with the naproxen and don't skip dosage. In a week , you will fell much better, or your symptoms will become more specific. Good luck. Keep me informed... Just take a break from lower body exercise. Maybe flexibilities or yoga only. Only within pain free motion."
So I did take a break from lower body exercise, and took Aleve for a week. I also researched cardio exercises for people with bad knees and tried to do that...for me that is so hard, because I just HAVE to follow a video or dvd, not watch the clock while i shadow-boxed for 2 minutes, but I tried my best..
I was really afraid of gaining because the regular exercise is my saving grace, it is very hard for me to restrict my calories (no will power) but I see that I really have to buckle down and find some will power!
but I am SO happy because my knee has been pain free for a few days now!
