Blood blisters in mouth.

[belle]

I have random blisters keep appearing on the inside of my mouth for no reason.

Any ideas?

My son gets these alot, he has hayfever and they seem to flare up when his mouth gets dry or scratchy with the hayfever.

His sometimes pop and bleed.

Are they on the roof of your mouth?

are they in your cheeks? have you been grinding your teeth in the night and nipped your cheeks?

No, i had one come up the other day while i was sitting watching tv. I noticed a lump on the side of my mouth, looked in the mirror and there was a blood blister.

I definitely had not bitten myself.

inside of your mouth is very sensitive, it could be anything from eating something sour/salty/hot to stress/tension. I have weeks where i just get one mouth ulcer after another for no reason at all.
