My lips have been burning and swollen for a few weeks. I cannot detect any allergy. I have treated for bacteria, fungus, and virus (Areva), have died to detect ingredients in lip stuff like beeswax/pollen and no relief. Today only using 100% vaseline, first time I tried this. Its the only symptom. I have tried to eliminate foods but nothing obvious. After intense swelling they peel. Only brief times since November of no symptoms. Red and swelling is beyond lip edge about an inch. Pretty healthy otherwise. I have been in two very different environments with same symptoms (Minnesota rural and Hawaii).
