Hi Sungirl1: Maybe you could bring up your concerns to your doctor and/or phone the clinic or hospital and talk to someone in imaging before you get your mammogram. I would think others may have had something similar.
I sometimes get numbness with nerve pain, especially in cooler months. Have you seen a neurologist for your issues? They may be able to get to the bottom of those problems.
Hope you get some answers. I am one to ask lots of questions (just ask my doctor, LOL!), but it always eases my mind in the end.
Best wishes and keep us posted!
