I have blistering in my mouth's right cheek.
When it grows big its transparent in colour. and fills with some fluid. my doctor says its nothing serious and gave me some oracort e paste and antibiotics. But after i finished the course of the antibiotics the swelling will still come. The oracort paste does eliminate the swelling. But after about 5-6 hrs..most probably after eating, the blistering comes back again. Should i go back to the doctor again? or are there any signs of oral cancer? Pls give advice Thanks!
