I have pcod, and have been suffering from breast pain before periods for many years. I have consulted few doctors and only tablet they gave was of primrose oil. I have taken that medicine for some time but had no results. Now the pain is getting worse with each menstruation cycle. The pain starts before 10 or 15 days of my period. Along with breast my arm pits also pain so much. I do the this ice and hot bag therapy which reduces the pain for short period of time. I don't know how long I need to suffer this pain.
