Hi thank you all again so much for your thoughts about my sister and myself. I think I need to be clearer on what I posted, they did not find a blood clot with the ultrasound, however they felt I had -had a blood clot and that it colud have been very serious. the vascular doctor i am soing to is well know to my family he treats my little sister who has had a stroke and my father who has some problems with his legs. So I am going to be checked out by him. they the er, think i might need to be on meds. thank you again for every thing. Sincerely, cz
