I was wondering If anyone is haveing problems with DVT's ( Deep Vein Thrombosis ) or Blood clot's . I am now haveing my third and biggest one yet in my calf and behind the knee.and it's very painful and Makes walking Very Very hard.I'm alredy haveing Major problems With imbalance and dizzieness, this makes it way harder to deal with. I had the other two in my arms and they were also painful but I didn't have to walk on them so the pain was easier to deal with. I always try to remain active despite the balance and dizzieness issues, I feel the more I do the less this PSP thing will be able to Take my life over. But come on three DVT's in less than three years, something has gotta be causeing this crap.I never had this problem before, I'm not Over weight, and My cholesterol is in check, I'm not dehydrayed and I'm not Diabetic. So what the heck is going on here?
