Hi, Thanks for writing your query. After reading your post,i would like to advise you that you can take antacid like Omeprazole 40 mg once a day before meals along with Domperidone 30 mg for relief from acid reflux. You should follow a diet with less spice and oil. You can take antihistamine like Fexofenadine 120 mg for your throat irritation. Painkiller like Ibuprofen can be taken twice a day after meals for severe pain. A throat swab culture can be done to know the appropriate antibiotic for the infective organism. Warm saline gargles will also be helpful. Local application of Benzocaine gel will help in curing the pain caused by mouth blisters. If the problem persists, get yourself examined clinically by an ENT specialist. I hope this is helpful to you. Thanks.
