OK, so i haven't been diagnosed with BD or anything, although I feel like i have an awful lot of the symptoms and that is why I am on here. I get incessant mouth ulcers all the time...they are always at least the size of my little finger nails and are incredibly painful. I often have several at the same time, and there seems to be no obvious reason for this. They go away usually within 2-3 weeks, after weeks of agony! I have spoken to the doctor about this and he said he could practically rule of BD because the ulcers last 3 weeks or more with BD. Is this correct? I also have had pain and tenderness all around my jaw, and am wondering if this is something a lot of people get with mouth ulcers?
