I'm 23 years old and I have been diagnosed with PCOS and it's been three months. From 28th Oct till today (20th Nov), I have been having severe breast pains throughout the day. On 18th of Nov my breasts seem quite swollen and on the 19th my right breast was more swollen then my left breast and the pain increased also under my right armpit. I have been asked by my gynecologist to take Dronis 20, Deviry 10mg, Metadoze - IPR and some Iron pills( as my hemoglobin was low). During this period, I took 5 pills of Deviry 10mg from 10th to 15th Nov to regularize my periods. Today is my first day of my period and I will be starting Dronis 20. what could be the reason for my breast pains and swelling? I'm afraid to take Dronis 20 as its leaflets shows so many side-effects and that i suffer from Migraine. Please help.
