one of the small veins on the underside of my tongue has come loose and is hanging. it is bothering me, slightly swollen, and the thread is hanging and gets stretched when I chew cause it gets caught in my teeth. What is this, what can I do about it, what should I do about it. I went to a walk in clinic, and the Doctor said he had enver seen anything like this, and to leave it alone, cause maybe it will heal itself. Not an acceptable answer. Ice seems to help. Will it reattach itself?
