my 28 year old daughter has had severe chest pain for 2 weeks. her left hand and foot started to go numb so she went to the e.r. sunday morning. her d-dimer test was a high positive. she had a ct scan which came back fine. the dr. thinks she had pleurisy and maybe a pinched nerve for the hand and foot problem. they gave her heperin and she keeps going in for blood tests w/ no change. They say she has a clot, but they can t tell where she has a dr. next week. She is in Hawaii and cannot come home until the d-dimer is lower (?) AND she does not have medical insurance. Any suggestions what else this could be?
