I went to my GP last week with painful lumps in my arm pit, swollen lymph nodes and sore throat. She gave me a z pack said I probably have a sinus infection in my arm pit. I finished the z pack. I still have the bad sore throat, no fever, but my lymph nodes are still swollen in my arm pit and my breast feels bigger than usual. I found a large bump on the bottom of my aerola i squeezed it some white discharge like a pimple came out. It has gone down. I m thinking coincidence. What next step should I take. I am a 55 years old female.
