I fell about 3 weeks ago on concrete. they said I hit so hard that I bruised my kidney. I went to hospital for dehydration,and then I had phemonia. I was in the hospital for 6 days. Well they came in saying my heart was going wackol it was going way down. So he mentioned maybe a pace maker which scares me. My legs were so swollen but they r going down. My legs hurt and my sides, butt and etc; I would like to know how its gonna be this way?
