I also have a similar situation. This may need to be treated with traditional Chinese medicine, but the process is relatively long and I usually can’t persist. Therefore, my lips are not getting better over and over again. Later, I found a method on the Internet. Use chlortetracycline eye ointment or earthworm eye ointment to rub the affected area three times a day. It cannot be said that it is completely cured after applying it, but the swelling, pain and itching are reduced a lot. You can try it.
