Hello everyone, I have posted here a few times over the past year after reading some threads I found "googling" about having high vitamin B12 levels show in blood testing. I have had 3 different blood tests to check my B12 level in the past year and all have come back over the range, as has Immunoglobin A (igA), I have been to a Hematologist to rule out proliferative diseases such as Multiple Myeloma, I had various blood tests done all which were negative and I was discharged. Other things linked with high b12 have also been ruled out via blood testing. I know from reading various sources that B12 is absorbed via the small intestine, and igA is also found mainly in the intestinal tract., However I have been tested for Coeliac disease and that was also a negative. Is it possible that I have Gluten sensitivity still without having Coeliac disease? or even having some functional deficiency with B12?, my doctors right now have basically left things as they are and refused me any more testing to do with these abnormal levels but they remain a mystery. I am also symptomatic of something, again lots of tests have been done and nothing found so far other than the abnormal b12 and igA levels, my symptoms are as follows and in order of how they manifested. Headaches Facial Pain Speech problems - tripping over speech. Memory problems - recalling things after they are needed. Increased Salivation - even dentist noticed this. Pins and Needles of my hands Burning sensations of my hands and feet Burning sensations in random places - as if someone has poured acid on me briefly. Itching all over body - comes on for a few days then disappears for maybe a month or so before coming back. Increased and excessive sweating - usually in response to heat but the amount is crazy. Fatigue/sleepiness - feeling exhausted by around 4 pm and have fallen asleep at my computer chair many times. Facial Flushing - Dry flushing non sweating. High Blood Pressure - found at the docs office, currently need an ace inhibitor and beta blocker to control. Muscle Fatigue - this is new to me over the past month, my legs in particular fatigue within a couple of mins of walking and feel very heavy and ache, however they can continue to do whatever it is I'm doing. Most of these symptoms are transient and come and go repeatably, also the sensory problems are symmetrical all the time. Do these sound CFS/ME to anyone and is the b12/iga linked with this?
