I do not know how it's called in Chinese, bursa, is a place where contains a special fluid synovial fluid, which help to decrease the frictions between bones where bones undergo abdutions and addutions movements....

I had this pain for several days, but i didn't really take notice of it....Sharp pain, stiffness, it feels pain during walking or any movements, all i can do is just sit and lie on my back.

Those small small bottles are called ampules, ampules contains different kind of solutions or powder drug, they are antibiotics, anaesthesia etc for external usage. just mixed up everything and put some cream, which is anti inflammatory cream on the affected area, and perform knee bandage.

estimated healing time: 10 days
