I have a lipoma under my armpit and sometimes it gets really itchy and annoying. Is this normal for a lipoma?

Thank you for sharing your question.  In some instances a lipoma can irritate a surrounding nerve which could cause these symptoms.  Alternatively it would be important to rule out breast tissue as being the cause.  

Lipomas are benign fatty tumors that occur under the skin and less commonly within the muscle. They are associated with mild discomfort and a lump underneath the skin. It is always best to talk to an expert plastic surgeon to determine whether the lipoma is possibly a cyst or a tumor or hernia. We would have to remove the lipoma to be sure that it is not something else and we usually do this by sending it to a pathologist for evaluation. If a lipoma is painful, then an exam is needed to make sure it is not compressing on a nerve or whether the diagnosis is different. Aftercare for a lipoma includes gentle compression and Plato’s Scar Serum twice daily on the wound.

Lipomas are not normally itchy. That is not to say they could never be but it would be unusual. They can be tender particularly angio-lipomas.I would question if your lump is a lipoma. Could it be an epidermal cyst for example which are more commonly itchy especially if they are becoming infected.Without examining you it is not possible to give you personalised advice. I suggest you see your GP for advice.Best wishes.
