I have had neck pain in the back of my neck for about 3 months. At first I thought it was stress, but I also have glands that swell off and on. My throat would feel swollen and I would think I was getting sick, but the next day I would feel fine. This happened for about two weeks. Then my left armpit began to swell. It, also goes up and down. I thought maybe I had mono or was allergic to my deodorant, but it just doesn t go away even though I have changed deodorants and am not having flu like symptoms. I went to my gynecologist and she felt a lump in my left breast. I had an exploratory mammogram and an ultrasound, but they said I was fine. My gynecologist says that I have dense breast tissue which could mask a lump during tests like I had. She wants to recheck me. Are the neck, glands or lump issue related? Should I be worried? I am 52 years old. YYYY@YYYY
