[|Human|] I went out for a party saturday. I didnt eat all day so i know it has nothing to do with food. Sunday morning when i woke up i had a hard very sore lump on the roof of my mouth since then the entire roof of my mouth has turned a purple bruised colour and it is incredibley painful to swallow at all. Any ideas?
[|AI|]  Hello, Thank you for consulting with Chat Doctor. There can be many reasons for this soreness of the roof of the mouth-First it can be possible that it is an allergic reaction to some chemical or solution-Second it can be possible that there is an infected tooth in the upper arch which is causing this abscess on the roof to diagnose it you have gone for an x-ray for which you have to visit a dentist and get complete examination done. Till then, you can start with topical ointment as McCoppin. Hope it will help you.
