Suggest Treatment For Fever And Sharp Pain In The Abdomen
Hello and Welcome
I appreciate your concern
The gastritis symptoms in association with the rash / blisters point to an allergic cause. Ranitidine and cetirizine both can be prescribed which are H 2 and H 1 blockers. If the symptoms significantly improve with these medication then it would be even more evident that there was an allergic cause. Empiric therapy can be advised in this regard. The triggers should be isolated and stopped. These include supplements , drugs and certain food products. Allergen testing can also be carried out.
Wishing you best of health
