What causes blood blisters in the mouth?

What is the cause & treatment for blood blisters in the mouth - I have 6. 3 on the tongue which are very sensitive. I have been putting 1/2 lemon in my tea and also using a herbal remedy TMJ mouth spray, which I have stopped using. First blisters appeared yesterday and are worse today.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

Understanding your concern. As per your query you have blood blisters in the mouth which seems to be due to canker sores, hot and acidic food, any injury to mucosa, stress, hormonal changes or some medicines and could be due to systemic conditions such as Stevens Jones Syndrome. They usually go away within few days by their own.

I would suggest you to :-- Start doing warm saline and baking soda rinses.
- Apply orabase gel before having meal to reduce burning sensation.
- Also start taking Vitamin B complex supplement.
- Do betadine rinses also for twice a day.

If condition doesn't subside in a weak then consult oral pathologist for proper diagnosis and then go for biopsy by taking sample from oral mucosa. Doctor may prescribe steroid ointment or drug like sucralfate .

Hope I have answered your query. Let me know if I can assist you further.

I came home from South Africa with mouth blisters- bleeding. They think it is Lichen Planus triggered by Malerone. Bioposy and all blood tests negative. I get blisters on my gums randomly- I have been using Flucisonide which helps but it never gets totally better. Now one dentist prescribed Valtrex. No Pain- just annoying all the time and worried about eating.
