Numb toes and arms. Having blood test Weds for everything under the sun, diabetes is suspected but could be anything. I had pneumonia many months ago, I have terrible asthma. I now cant fill up my lungs and speaking or moving is a chore that makes me dizzy and very breathless. I am very tired. I dont know what to do anymore. Should I just chuck it in and turn up to a&e? I've been to gp he just wants me to wait for blood test weds but I can barely function.
