I'm 18 and I've had this problem for more than 5 years. I have to use a certain lip balm because most lip balms when applied to my lips first give me a tingling sensation within approx. an hour and when I wake up the next morning they're swollen, especially the upper lip, and it feels quite uncomfortable to move my lips.
They do not itch and burn only slightly. Many tiny bumps (the same colour as the skin they appear on) emerge on my lips on the second or third day and begin to spread on the skin around my lips, usually above my upper lip. My lips tingle when I touch them. These symptoms last almost a week and in the last days my lips start to peel a little and they begin to feel normal again - as in, I can freely move them without feeling discomfitted.
Years ago, I used Nyal Cold Sore Cream because I thought I had a cold sore. This contains 5mg menthol and 15mg camphor which soothes the discomfort. At the time it worked for months but then later it began to give me these symptoms as well and I had to find another lip balm. I returned to this cream last year and it worked again for me, but, after not using it for a month, it started making my lips tingle again so I stopped.
I don't know if this is an allergy because my lip balms keep changing. Does anyone know what it is? And also anything on how to soothe them, improve healing, prevent, or what to do or not to do during these symptoms.
