My lips are a little swollen but its the inside of my mouth, like behind lips that are hurting... itchy,tingling, sore. Also my toungue a little bit. This has gone on for about 2 days. At first I thought I had sun poisoning on my lips, but that wouldn't bother the inside of my mouth. I started researching and found out about angioedema. It sounds like that may be what I have but not sure.The only thing I can think of is I used a new mouth wash. Would that trigger this? Ive never had any problems before. Should I be worried?
