question: About 18 months ago I discovered a lump on the back of my neck, right on my spine. About 1 1/2 wks ago I awoke and my whole body felt like it had been in a vice all night. I thought I was coming down with the flu. My whole body was painful to the touch.It lasted for 3 days and never had any other symptoms. Then a few days later this lump started becoming sore and got bigger. There is no head to it, I tried putting a hot compress on it for a couple of hrs. to see if anything would come up and nothing has. It is about the size of a quarter. Also, a red rash has developed in my hairline next to the lump. Im not prone to anything like this. Im a 45 yr. old healthy female. Any ideas on what it could be or any treatments I could try? Should I be worried?
