Hi there, basically I play basketball 4 times a week. Recently when I play my knee calf and ankle start to ache half anour in, it gets worse as time passes so I just stop, go home and rest it, on Thursday night I played and it really started to hurt.. worse than it has previous, the next day when I got in the shower I had a small bruise on the inside of my knee, and a bigger one on my calf, what do you think it could be? Thanks very much, D

Have you started taking any kinds of medications ? Sometimes certain meds have an effect on your blood vessels. Such as blood thinners or even low dose aspirins i.e baby aspirin or low dose pain reliever aspirin. I would definitely talk to a doctor about this though, could be serious?!
