Hello - I'm a 23 year old male who's a non smoker, fit & healthy and from the UK. Over the last 3 weeks I've been having these red blood blisters appear in my mouth on the inside of my cheek where my teeth align (if that makes sense). At first I thought it was just where I may have bitten the gum numerous times or burnt it somehow but it's the forth time its come back and im starting to get worried. Not sure if ive only started noticing cos I don't normally check. It normally heals within a couple days but then just comes back in the same sort of area. I appear to have no other symptoms and haven't noticed anything different. Are these common ?
What could this be ? I've read it could be mouth cancer which terrifies me but for someone of my age and situation it seems unlikely. Are blood blisters a sign of this or are there other symptoms also? Thanks
