right breast pain

Hello. My name is Jamie and I have been experiencing pain in my right breast. It is a throbbing, pressure pain. I have also been experiencing flu-like symptoms along with it, but no fever. I am not sure if I should be worried or if this is something that will pass. No I am not a mother, so I am not nor have ever breast fed. Please, if you could assist in helping me figure out what I can do to stop this pain, I would be very greatful.
