new worries

Kinda trying not to freak out right now.  All week I've had an area on my leg that felt warm.  I don't know how to describe it any other way.  Not warm to the touch, just a warm sensation, like it feels to me that the area is sunburned but it's not at all.  I've noticed pretty often and just told myself to dismiss it, that I'm just being a worrier.  Now it feels more warm and noticable.  And now it's swollen a bit too.  All classic blood clot signs.  I've been trying not to be overly cautious, but now I can't ignore it.  I called my regualr dr's office and they just returned my call, advising me to go to the ER.  Great.  The fun never ends...
