I was in the hospital for 2 days, 4 days ago and during that time I had an IV going at my left wrist. Now my forearm half way between wrist and elbow is warm and there is a noticable (inch) lump, and a new bruises on the inner left elbow. The vein is swollen and darkened about 2"+/- from wrist to elbow. Does not really hurt but you can see it and it feels somewhat hard & warm.
