I have been to the doctor twice where they did blood work and urine test. Blood work was fine and I had a bladder infection that I have taken antibiotics for. My symptoms still persist off and on. Headache, nausea, stomach pain, chest pain, left arm pain,red circle rash the size of a quarter on wrist, head and facial numbness. EKG was fine. Do you know of anything this could be that would not have showed up in the blood test? My antibodies in blood work was fine as well.
