[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  You are taking Coumadin, so you have some bleeding tendency.  That's why you have large lump.  If you have more bleeding than you should consult your doctor.  Antidote of warfarin like it k is useful.  It is prescription based medicine so consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
