[|Human|] my husband has a blood blister in his mouth they have been coming and going for over four to five weeks now could they be caused by the large amount of medication he is on - the Dr has refered him to the Community Dentist yet our own dentist asked him to see the Dr
[|AI|]  Thanks for your query, I have gone through your query. The blisters could be because of the viral infection like herpes zoster infection, or it can be Memphis or pemphigoid. Consult an oral physician and get it ruled out. If it is a viral infection you can take a course of antiviral Chat Doctor. If it is Memphis or pemphigoid you can take topical steroids like triamcinolone acetone (0.1%) 4-5times daily for 1 week. You can also take topical anesthetic and analgesics like Anabel gel for the pain. If the lesion does not heal then get the lesion biopsied to confirm the diagnosis. I hope my answer will help you, take care.
