Over the last 8 or so months I have been experiencing the following symptoms on a regular basis: numbness from headato toe, sometimes more severe and in random spots more pronounced than others, with a overall loss in sense of touch; head aches; stiffness and soreness even with out any exercise or over exertion.Other symptoms that happen more sporadically: sleeplessness; chest pains; faint pulse; cramping including in the chest and abdomen sometimes seeming to be my diaphragm cramping/spasm; blurred vision with migraine head aches; loss of appetite; shortness of breath and metal taste. Not all of these always happen together or with the same frequency. Doctor has tested for metal poisoning: zinc lead mercury, hepatitis, aids, and vitamin deficiency all which came back negative ct scan from a hospital visit found no fluid in the brain and no tumors.Sometimes the numbness is random like part of a finger or hand or face well be numb and have a pins and needles feeling other times like when working with my hands above my head they will go numb and get stiff as well as my legs if doing stretches while laying down and my legs are elevated.
