Two years ago, the cracks of my mouth split while I was yawning. I put Neosporin on them, but to no avail. In addition to further protect them, I started putting chapstick on my lips. And then suddenly, my lips started to itch terribly. Ever since then, I have been unable to rid myself of cracking, itching lips, that are slightly crusty and scaly. I also notice that if I look closely, I can see very, very tiny pimple-like dots on my lips. Also, if I press my lips together, I can feel a slight wetness, probably from a liquid emitted from the small dots. I have never had any sort of lip issue, nor have I ever been allergic to anything in my life. Since then, I saw the doctor once who prescribed me with some sort of steroid cream. She told me that if it went away with the use of the steroid cream, that meant I was allergic to something. The itching did indeed go away. So after I was done using the cream, all the symptoms returned. I have changed my face wash, lipsticks, makeup, toothpaste, anything I could possibly think of that possibly touches my lips. I have also changed what I put on my lips. I have used everything from Chapstick with Petroleum jelly, to just petroleum jelly, to natural lip balms without any petroleum jelly, olive oil, Lansinoh, benadryl cream, Lanacane, Hydrocortisone creams, etc. I have used nystatin because that was also what the doctor had prescribed thinking it could be a fungus. It has also been ruled out by the doctor that it could be a Vitamin B2 deficiency. The terrible itching continues so horribly that it wakes me in the middle of the night out of a dead sleep. I have also been to other doctors who are perplexed at my issue. I'm desperate for some answers! Could anyone possibly provide any insight as to what this could be?
