Before I settled on the surgery, I had every test imaginable. Skin biopsy. Lumbar puncture. EEG. Aside from the ankle reflex...which is toast....all other tests were inconclusive....accept for that little blip on the radar....MGUS. There, again...the confusion continues. Paraprotein .1 (very small) as the haemtologist said...a freckle....she said most don't even know they have it, unless they have other symptoms. My IGA...IGG...and IGM all fall within the normal range...so why...why...why? Did all my years of drinking cause it? Why am I anemic? All B12 tests normal. Never tired or weak. But RBC is 3.9....low! It is so frustrating.
