my right breast nipple hurts

From what you are explaining, you have blocked mammary ducks in your breast(s). You will need breast massage(gentle ones at the start) to help relieve the pain. Are you wearing Underwire and Push-up bras? These types of bras will do this. They will also cut off the lymphatic and blood circulation systems. You should avoid them.

An other problem which you might have, is that you have pinched and dislocated nerves in your mid and upper back areas and they must be reset soonest. I know as I have been a Healer for more than 14 years.
