Hi I have had recurring mouth ulcers for about 2 months now they last for weeks and weeks and go then come back again and last for more weeks and weeks. I finally went to see my doctor about it he said I have to be transferred to hospital urgently to see oral and maxillofacial surgeon which I will be seeing this week. Also had blood tests done but haven't had results back yet. Current mouth ulcers that I have in my mouth I havs had for 5 weeks. I'm worried if it's anything serious.
