I woke up this morning with painful, swollen lips. This happened once before, about 2 years ago. I went to the doctor and he put me on Valtrex and assumed I had herpes. It didn't help. However, during this time I was constantly applying Carmex. As soon as I stopped, the swelling and pain went away. Three days ago I purchased Chapstick Moisturizer and now I'm back in the same state as I was 2 years ago. So, I'm assuming there is something in Carmex and Chapstick Moisturizer that is causing this problem. I will take a Benedryl and cross my fingers. Any recommendations? Thank you in advance.
