Clot?

I've been perservering with some pain in my left calf for a while now. It feels like it's constantly cramped. I had just assumed it was probably a muscle strain but after talking to a friend I decided I better get it checked out in case it was anything more serious. Anyway, I went to see the Doctor about it last Thursday and they referred me to the Nurse Practioner's Unit at the local hospital. They looked at the leg and said that it was likely to be a muscle strain rather than a clot but since my Dad has a history of DVT they would arrange me to have an ultrasound on the following day.

I had the ultrasound on Friday; it involved a couple of hour wait during which time I made inroads into Bret Hart's autobiography. They only scanned the top of my leg and when I mentioned that the pain was in my calf they said that they were more concerned of a potential problem further up and would only scan the lower leg if the pain continued to persist. The results show that I don't have a clot in my upper leg; which is a relief, but doesn't leave me any the wiser about my calf.

Anyway, it's been almost a week since I first went to the hospital and the pain in my calf has abated somewhat. It's not gone; but, it's nowhere near as bad as it had been.
