[|Human|] i have noticed what looks like a blood blister on the inside of my right cheek. it doesnt hurt but i looked at it and it seems like a swollen vein or blood blister. its dark purpleish and too high for where you would normally bite your cheek i think so i dont think its from a bite. i felt it there a few weeks ago and it hasnt changed. its about inline with my teeth in hieght in the cheek...?
[|AI|]  Hello have gone through your query. Most common cause is trauma or irritation of the mucosa of the cheek.a muscle can also occur at that place BT normally it's not red. Are you having any amalgam restoration in the adjacent tooth.it can cause black discoloration of mucosa called amalgam tattoo.a lipoma or fibrous can also be seen at that place. Watch it for few days for any change in the blister. I suggest you to visit a dentist to have an examination. Hope this ans helpsRegards
