Hi I had suffers from upper abdomen pain few years back, and now it has started again. I mostly get this pain middle of the night. in 2012, after few consultation and medication, Dr advised for an Endoscopy which detected H Pylori infection. Took the medication, though it did not cure immediately, but after stopping medication it went off. Now similar problem, can it be H Pylori again? right now just takin PAN 20 twice and some doc gave Vizylac capsule to be taken. Can i also take B12 as level was low. Please suggest.
