Last week when I started this thread I opted not to go the the doctors. (Plus it was the weekend and I was not willing to spend it sitting in an ER waiting room) The pain eventually left and visited other areas. However today it returned in the calve and since you guys got me all worked up about clots last week I googled pain behind the knee, (which is where I believe the pain comes from). It said there was a thing called a Bakers cyst. I decided to call my doctor and they let me come right in. He felt around and said it does not appear to be a BC or a blood clot but since now I have a history he recommended an ultrasound. I was able to get into a nearby medical center where the tech did her thing and let me go. Saying off the record that if she thought there was a blood clot I would not be allowed to leave the office. Both visits combined were only 2 hours. If I didn't call work they would have never even known I left and then returned. So I am out two $25.00 co payments but I guess better safe than sorry.

Now I have to wonder if this is nerve pain. It centers behind the knee and can either be in the calve or the upper leg to the butt. I lowered all my computer chairs as I realized I had them too high and was putting a lot of pressure on the back of my upper legs. Thank you all for your concern and advice.
