I have an irritation on my hairline (in the center of my forehead) then realized I had swollen Lymph nodes. I did not think these symptoms were connected so I applied zit zapper cream to the irritation thinking it was a break out and it seemed to scab up like it was four little pimples connected. Today I woke up and have a lump underneath the irritation and its red and itchy. I am becoming very concerned. What should I do?
