I am a 61 year old male. My lips are red, chapped, swelled and dry and have been for about 2-3 weeks. I have been applying Carmex, which helps a little, but on temporary. I have researched this and considered a possible reaction however, I cannot isolate a commonality which may be causing this condition. I have been on a prescription drug for over 4 years and nothing has changed where this is concerned. Any questions or possible diagnosis for my symptoms?
