Had stomach bloat doc put me on zantac (ranitidine) for ulcer did blood test to see if i had h.pylori that came back clear what is the next course of treatment?

Scope: you need to be properly diagnosed so you need an endoscopy to make sure what do you have and that will decided the next course of treatments

Ulcer: Zantac is good because it works immediately. If you persist in having pain consider a PPI like omeprazole ( prilosec) , or carafate (sucralfate). Also if you are having persisting pain recheck the blood H pylori in 6 weeks , because it is an antibody may take 6 weeks to be positive. Breathe test for H pylori may be more accurate now but you can not be on stomach drugs for it
