Dermatology Questions? Ask an Online Dermatologist.
Hi there, Dr. Mires here to help answer your question. Please try to provide additional information as best as you can. Is there any way you could submit a picture of your forearms?
How long have the lumps been there? Did they start small and get bigger? When you say lumps, you mean they are raised up as opposed to pits (small depressions) correct? When did you start taking Coumadin, and if you had the BB sized lumps on your skin before starting Coumadin, did the Coumadin make them bigger?
