@Boris: oh about five years ago now i got a infection that went down tot he bone, for the longest time they couldn't figure out why it wasn't healing likei t should, cause i do everything they tell me, i went to see a leg specialist and we found out some of the veins don't close liket heir supposed to after blood goes through them, so dirty blood comes back into the area mentioned. so what their gonna do is close off the bad veins, to give the healthier ones a chance to help heal the wound. apparently its like a 99 percent success rate. tis jsut a little cut and some sonogram though i did ask to be put out, as i do not want to panic and punch the nice doctor trying to fix my leg.
