i had surgery very high fever – rushed back to hospital feel like i’m being poisoned?
i do not think your back surgery is related to current symptoms except for your immunity has dropped down dramatically after it… i think the symptoms you are cimplaining is related to immunity weakness and low white blood cells. also you may be having a chronic gastric disorder that might be ibs … i recommend doing a cbc and abdominal usg. a gi specialist then can follow
