hello i am a 25yr old mother of three,over the last six months i have noticed an increase in tenderness and pain in my breasts,only recently my partner noticed i have discharge coming out of them..could this be old milk or hormone changes..and can old milk cause problems? i also have a IUD and have had it for hmm about 3yrs..i am currently experiancing pain in what i believe could be my left ovary..feels more like in the back..hard to tell if its my kidney hurting or if its jst my period..could all these symptoms be to do with natural prosses hormonal changes because of my age ?or could there be someting else going on with me what are the signs i should look out for if i think it mite be cancer in and old blocked milk duct could the milk stuf be tested?what colour breast discharge is normal?
