Thanks  all, for your advice/help. 

Raven, what did i do? Well, i was just on break( at work) and i decided to do a kick(karate kick). That's it.  I didnt fall, but something got hurt i guess. although at the time, all i felt was alittle pain. I had no swelling, no discoloration, not even much pain so it's kind of weird. i've never had any visible swelling since i had that injury and it's been 2 weeks now. I also never had much pain.

, what i've having now is strange ligament knots, so i haven't been able to walk. However, i think i'm getting better because i'm getting less knots and i can walk  now and avoid knots by walking in slow motion. 

I also had this thing where everytime i get in the shower, i'd get knots when lifting the knee slightly so these days i've been scared of entering the shower. but today surprisingly, i didn't get knots when i lifted my knee slowly. So maybe there's some healing going on here. in fact i've started to walk with less or no knots starting yesterday. I've been taking care of the knee so i gues s that's helping too.

Ortho checked me and said my knee is stable, did tests and manual tests and i didnt have much of a problem or pain. Although it seems to happen that whenever i go to drs, the symptoms do not come up.  

I have this weird mind because i get an impulse to do something  and i always do it before thinkking. That's how i also hurt many other body parts. 

And it seems i have injuries every d*** year. It doesn't stop. i can go year by year and tell you of major injuries i've had since i was 6.  I dont want to get injuries but it happens cause  i guess im stupid.

By the way Kneegeeks.....seems that site is all against me or something. Everyone gets responses except me. For some strange reason that happens in other healthboards too, everyone gets responses and my response count remains at ZERO forever. 

lululee, thanks for the advice. I am taking some supplements too.
