I just posted this, but for some reason it never showed up as a new thread. I need to know if there could be a connection between severe gastritis caused by a h-pylori infection which I was treated for 11 mos. ago and confirmed erradicated and small nerve fiber neuropathy? I am on B-12 shots monthly and 1500 mcg of b-12 orally on a daily basis, Pain is severe and comes and goes.....gastritis causes pain and burning in the stomach area and when this is going on the neuropathy symptoms are bad....when the gastritis calms down, the neuropathy almost completely disappears. Gastritis causes nutritional absorbtion problems is what I was told....The neuropathy was diagnosed as idiopathic in 2009 and have suffered greatly from pain, numbness, sexual dysfunction and tremor. Anyone that could help me, pls. reply and thanks in advance!
