hi everyone,
i m suffering from certain problem about which i have never heard of.
every 5-6 months i fall. ie. i m walking normally and suddenly my left knee folds automatically and i feel immense pain and i just collapse coz of it. It has happened 4-5 times in past 1 & 1/2 year. Following this i have great problem and pain in folding my knee for next 4-5 days. Then slowly it turns normal again.
It appears that my knee comes out of joint and i shake with pain for 5 seconds. I m very strong at heart but the pain and fear makes me cry. I just shrugg when i imagine if it ever happens on road or while i m cycling or something. I m a 15 yr old guy.

PLEASE SOMEONE HELP. ANY DOCTORS HERE???
