Swollen tongue? my tongue swells on and off for no apparent reason. i have been to my primary dr., dermatologist, and ent and no one knows why. i have tried to identify a food that may be causing it to swell but it's too random to be connected to anything

Without : Without seeing it, it is impossible to tell. If you were my patient, i would refer you to an oral maxillofacial surgeon for evaluation. Just to let you know, they will probably have to biopsy it. There are a few ways to do that and does necessarily means cutting it. Most oral biopsies start with a scrap method, usually done with a wire brush and just feels like a little scratch. Check out macroglossia on webmd.

I : I think that it is very important that you consult your regular dentist first at a time when your tongue is at it's worst. You can see an oral surgeon or if necessary an oral pathologist for evaluation. If it was me, i would even go to 3 or 4 (or more) specialists until i got an answer. In almost all cases, you should be able to get a proper diagnosis of the cause.

It : It wasn't mentioned when the problem started. Is it merely your tongue that gets swollen? How about your lips, cheeks, and throat? Anything that can block the airway is a serious matter and is life threatening. If this is an angioedema and the source is not identified, it is life saving to visit an allergist before it becomes a full blown allergic reaction. If you haven't seen your dentist recently, make it sure that you don't have teeth infection (esp if roots are already affected) that can cause cellulitis, e.g. Ludwig's angina.That can also affect the tongue.
