I was to the doctor yesterday.  He said he feels pretty confident that the blood thrombosis will reabsorb.  He told me a clot is a solid grey bass on the scan and what i have is a swirl.  I asked so what does that mea?  He said it is not solid, and he feels it will reabsorb.   they are going to check it again with a tee at the end of September. Wish me luck.  At least now I have a little more optimism now.
