question: Hi doctor, I am finishing the last part of my treatment for breast cancer. About a month ago, I started having numbness and tingling in arms and hands. It wakes me up through the night. I just recently started working in a grocery store, which is very physically demanding. It lands me with endless knots in my back, neck and shoulders. I was rubbing the knots out of my neck tonight and I got a little dizzy.  It went away, but now three of my fingers on my right hand feels numb and painful. I am wondering if I should go to the emergency room. My oncologist is about two hours away. I am a 48 year old female. I had a lumpectomy before two months with a partial node biopsy.
