Breast Pain

Hello, I am new to this forum. I am 43 years old, no family history of breast cancer except my grandmothers half sister had a tumour. I am on Zoloft for anxiety and a beta blocker for heart palpitations. I have had left breast pain for two months now on and off. I had my mammo two months ago and it was fine. The breast looks fine, but all through the day on and off I get a burning pain and sometimes shooting pain. When I press deep in some areas of my left breast it feels very sore. My breast are generally lumpy, some moveable lumps all different sizes and have been that way for years. I read on the internet that breast pain doesn't usually accompany breast cancer, but I have seen some posts on here that says otherwise. I plan on going to the doctor just to get it checked but i am really scared of what the pain could mean. I feel like I am running to the doctors left and right this past year. I am havin bad stomach problems with acid reflux for the past month, as well as heart palpitations, both which I am seeing doctors for. I have spinal stenosis which lead to a pinched nerve three years ago so I have pain on and off in my arm, shoulder/neck. This breast pain also feels like it radiates under my left arm , not in the armpit, but the bone so I am wondering if it is possible for the breast pain to be associated with the pinched nerve? I feel somewhat soreness when I probe both breast, but the left one is worse. Just looking for any thoughts if anyone had had this. Thank you for any feedback.

Straydog, thank you for your thoughts and encouraging words. I do plan on getting this checked, especially if the pain does not go away. I have a way of letting my mind go straight to the worst of possibilities with everything in life. You are so right, stress & anxiety definitely take a toll on our bodies, it has for me.

Thanks again
