Hello, I'm only 21 years old and haven't posted on here before, but I really need some advice as I'm getting a bit worried to be honest.
Around the week before my period is due I always have sore, tender breasts. Last month, this was accompanied with some pain, I felt the area and there was something that felt like a lump but I wasn't sure. Period is due again soon and I have breast pain again and there is definitely a hard lump there. It is the area sort of to the side of the breast, under my armpit. I'm worried now - could it be a cyst or something more sinister? Has anyone's else experienced this around their menstrual cycle?
