my lower lip started getting tingley, and started swelling this started about 3 hours ago and felt like it was going to crack open. I had not been bitten, nor had I had anything for breakfast except coffee and a donut. I had not taken any of my meds. before noon. the lips had bruise (bluish looking) corners. any other possibilities? I had no pro0blems swallowing. It has gone back down somewhat now.
