I am 20 years old and I've been suffering from mouth ulcers which last a really long time, the last session lasted approximately 3 months and now again, after a 2 month gap. They occur all over the tongue, beneath it and cover up the inner upper and lower lip. They are extremely painful, making it very hard for me to speak, eat or even move the tongue around, forcing me to grit my teeth firmly. I've tried various types medication but they all seem temporary and have short term results. I drink healthy amounts of water, so I don't think hydration is the problem. Just trying out my luck here, hoping that something would turn up that might really help. Thank you in advance! Peace
