Swollen Tongue, Left side only

I woke up this morning with a mouth full of saliva. I had difficulty swallowing it as the left side of my tongue was swollen to the point where I needed to open my mouth fully to place my upper teeth on it. My wife could barely understand me when I tried to speak with her. My face or jaw was not visibly swollen at all. It is now three hours later and it is almost normal.

Has anyone experienced anything like this? My thyroid numbers have been checked recently and all were normal. I have not experienced any dental issues of late either.

I have had Gall Bladder and Pancreas issues recently and have gone off all supplements and herbal ABX while determining whether to remove the Gall Bladder.

Not even sure which Doc I should call, or if I even should.

Thanks in advance.
