Well once again I'm having pain in my left leg. It's in my calf and the inside of my leg going all the way up to my groin. I've been trying to be really strong with it and telling myself it's just another muscular pain like last time but when I went into Dr's yesterday to get a requisition for a urine test I mentioned I had been having this pain since Wednesday so he wanted to take a look and said it was a little bigger then my right and a little warmer so he was suspicious and sent me to the emergency room. There the Dr didn't even look at it really but ran a d dimer and it was negative. Today it hurts worse then it has since it started but I'm trying to convince myself that's because I went for a little hike and stuff with my husband last night. And I'm feeling breathless but that could be my low iron as it doesn't feel like there's a weight on my chest at all. Is the d dimer accurate enough that I can give up these blood clot concerns and try not to worry?
