I have had a swelling that looks like an arch under my lower lip which my dermatologist says it is arciform area of swelling below the lip margin for almost 3 months. The first month she prescribed a cortisone crème to apply twice a day for one month and it hasn't gone away. She then prescribed a steroid ointment (mild) to use for 10 to 14 days 3xday. I am on the 10th day and it hasn't gone away. It is not red, doesn't itch but is so noticeable that I am ashamed to go out. She wanted to do a biopsy in the future but I don't want that. She mentioned angioedema but also said it could be just an allergic reaction from something. I am at my wits end and would like to know if anyone else has anything like this. Have a thyroid condition but is normal taking my Synthroid every day. I am 70 years old and have great skin. I just wonder if this is just my aging process but don't have any other wrinkles thankfully. Please help.
