Hi, I have trouble with my lips swelling on occasion. Went to doc and we guessed it was stress or something. Swelling would go away within an hour. However for the past four or five days, my lips just hurt. They are not dry, I put Vaseline on them every hour. Today, the pain is the worst it s been. Bottom lip beginning to swell, notice some purple discoloration. Have ice on them now. Help?
