My symptoms started one and one half days ago with only one canker sore. I have some very large, painful ulcers and canker sores as well as: small lacerations that sometimes bleed, open skin, and very dark purple and black veins under my tongue and along my gums.
Hi, Thanks for posting the query, Canker sores mainly occurs due to physical or chemical trauma, ulcerations can be due to trauma, nutritional deficiency, hormonal imbalance. I would suggest you to get a checkup done once. Take multivitamin supplements, tab vitriol. Apply Hegel oral ointment topically over it. Maintain a good oral hygiene. Take care! Chat Doctor.
