Thread: Throbbing Breast Ache, aching in armpit/shoulder

This morning I woke up with a throbbing pain at the base of my left breast, towards my armpit. It was dull as well, and achy. The area is tender and sore, even moreso now because I've been poking around trying to do a self-breast exam (though I never ever know what I'm looking for in those things). I am just nearing the end of my period as well, so I don't know if it's because my hormones are balancing out, or if it's something serious.

There is also dull, aching pain in my armpit, shoulder, and up into my neck, and it goes as far down as my left shoulder-blade and the joint of my elbow. For the past five days I have been home on mid-term break, and the bed I sleep on at home is less comfortable than the one at University.

Of course, I worry that it is something like breast cancer, or some terrible something that can't be treated by the doctors at the University's health clinic (they usually give girls a pregnancy test. The guys get condoms.).

I was wondering if anyone else gets these random throbbings towards the end of their menstrual cycle as well, or if I should worry about it.
