deep vein thrombosis
"I developed  a DVT in my thigh after hurting my back and being unable to get around for a few weeks, ended up in the hospital for 5 days on total bed rest. Shortly after a large DVT was found in my right thigh.  I was put on Xarelto for one year.  I have been on it now for 6 months and my leg and foot stays swollen, but does not hurt.  My hair fell out for the first two months and then stopped, I have had no other side effects.  I feel good with the exception of getting tired more easily."
