I don't know why but for the past 2-3 weeks I've had quite sore breasts, especially in the nipple area. I am definitely not pregnant and the only changes I have made is my medication. I was diagnosed with Hyperthyroidism/Graves' Disease back in August and started taking Propranolol (40mg x 2 a day), following my appointment with the Endo. I started taking Carbimazole (10mg a day) just last month. I have just upped my Carbimazole dosage to 20mg a day last Friday and I don't know if it's a coincidence but my nipples seem to feel even more sore, especially on my right side. I have been checking them, and both sides seem to be the same, I have very lumpy/thick breasts.
I am a bit concerned, I thought the soreness would go away but they are very sore this morning.
Any help would be greatly appreciated. Thanks
