Hi, over the past 24 hours I have developed several abnormally large and painful ulcers along both sides and the tip of my tongue. Within the past 6 hours or so I have also developed an ear ache, swelling on one side of my tongue, swollen glands in my neck, and am having difficulty swallowing. I am also under a lot of stress and am wondering if that is causing this, and if not, what is?
