question: i started taking cerazette about 6 weeks ago and i have this week developed slightly painful breasts that feel hard and a little lumpy. I was also bitten on the breast by a mosquito a few days ago. Most of the redness and swelling has gone but there now feels like there is a lump there, under the site of the bite. Could this be caused by either the bite or the pill? or could it be something more serious?
