It's not just my legs, but they're the worst for it. Probably 10-15 finger print sized bruises across each leg at any one time. I have no idea what caused them - I've not had any injuries/bumped myself/done anything that caused pain. They aren't actual finger prints - am single and not having sex ha.
I must be deficient in something - but what is it most likely to be, and I'll try and treat it with vitamins etc myself first before bothering a dr.
