Hi,I was diagnosed with thorasic outlet syndrome in 2011 and told that i had 2 extra cervical ribs,one on each side.was told that I did require surgery as I have the vascular type,after deciding not to have surgery because the vascular surgeon had only done the surgery 3 times before l have since suffered a mini stroke & my right arm and hand and fingers keep swelling,going completely numb I m unable to close my hand to grasp and pick things up,been to a&e on numerous,occasions when this happens to be told that I could throw a blood clot and when this happens and that this could of been what caused the mini stroke,just wondered is this true and could it happen again.many thanks
