Well thanks to all of you Im probably going to be ok. I have been referred to a vascular surgeon. the vascoconstiton from rsd in my orginal leg is so severe, on top they think i did have a clot in my leg. I was very lucky and should have gone to er right away as you said. I dont know waht will happen when I see vascular surgeon but looks like i may be put on blood thinner. i was really lucky- this could have gone to heart or brain. and caused a stroke. I go on thursday of next week. total numbness of a limb especailly with sudden onset is not normal- for anyone(this is what they told me) - rsd or not. I assumed it was another form of tortue form my rsd. That coupled with my sister could have cost me a great deal. Im still upset and frightened by the scare. thank you all very much for your help so so much. I will let you know what happens thursday. my very very best to all. I also can not thank you enough for your kind words and thought about my sister Cheri, she is still doing well- will not need open heart surgery and will just be on meds. this is the third person in my famiy with heart disesase or stroke so I guess my leg makes sense with the pattern. It's so scary what we suffer with rsd and what we ignore thinking it is more rsd, this was too close for me. my very best to all God bless, cz
