I have a stomach ulcer that is not caused by H. pylori, and it is not an NSAID ulcer as well. What can I do to completely get rid of this ulcer? I am taking Ranitidine for it. The ulcer has come and gone over the past two years roughly. The stomach ulcer was diagnosed by asking a series of questions and by touching my stomach area. I have anxiety and depression, so stress is likely the main cause, according to my physician, and I smoke marijuana. My current medication includes Ranitidine, Trintellix, Clonazepam, Tricera birth control, and Zopiclone. I am also taking multivitamins and probiotics, which are self-prescribed.
