Hi, my lips are burning, itchy, red, & just started to swell up around the corners & top of my lips. I did not eat anything that was different from my normal eating habits, I was not in any different area that I don t normally go, there was nothing out of the ordinary of my every day life style so I m not sure what is going on. It has been like this a few months back. I got some Burt Medicated chap stick which helped out well but it s back again just after a few months... should I truly be concerned?
