I have several sores in my mouth. It started on my lower lip as many very small bumps. They are not canker sores and now they are on the underneath of my tongue.  they are red an hurt. I have been putting a NSAID topical creme on my hand could this be a reaction as I have had asthma related allergic reactions to motrin in the past
Hello Welcome to Chat Doctor, I have gone through your query. As you have already suggested that you have shown allergic reactions to Motrin in the past which is also a NSAID(Ibuprofen). The mouth ulceration in the floor of your mouth is most likely caused as an allergic reaction to the NSAID ointment you rubbed on your hand. I would like you to visit your nearest Dentist to rule out any other cause. If you were my patient, I would have prescribed you with a Steroid Triamcinolone Acetonic cream 0.1% Mouth Ointment or any Topical Steroid If you were not allergic to steroids. Moreover, avoid spicy foods and Eat and Chat Doctor.  Rinse your mouth with Chlorhexidine mouth wash. Thanks and
