No joy today. Lots of tests done with Rheumo and Neuro consultants. Not interested in B12 active test which shows need further investigating (40.5) Range 25-165 and free t3 3.7 (3.1 - 6.8). Still tingling/burning/vibrating through body. shortness of breath. legs ache intensely just walking up stairs. Fatigued. Few nodules on thyroid from ultrasound. Taking supplements. Now suffering heartburn. Hearing loss dropped 3x now deaf one ear.Tested for peripheral neuropathy. Dry eyes. echocardiogram and ecg normal. Seriously considering private Endo now as I have symptoms of both B12 and thyroid. Anyone any suggestions??
