<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctors,Just want to know this sign on me..I got my menstration period over few days back then suddenly..got a bit pain under on my armpit and the pain goes to my breast on the right side theres a portions of soft lumps on it..is it just connected from hormone cycle changes or any serious matter?  <response>: Hi. Normally the hormone dependent lumps regress after the menstruation, which you say has been over a few days back; so does not look like hormone cycle changes. This can be a sort of infection in that area which has caused all this. Please consult a Surgeon to ascertain the cause and decide the management and to rule out any serious matter; which I not think it is. So do not worry. This looks to be an infection only and will settle with antibiotics and anti-inflammatory medicines. IF still persists after 7 days or increases in size, pain, redness, please consult a Surgeon ASAP.
