Re: Hard lump on back of Head. PLEASE HELP
I have two, one on each side. I am 46 years old and have had them for as long as I can remember. About a year ago the one of the left side got really sore (not the first time one of them became sore though) and I found about two weeks later that I had a sinus infection on that side. For the first time I told my doctor about them and was told they are lymph glands. This is the reason for the soreness when I got the sinus infection. So, I agree. It is probably not serious, but if the lump is feeling different right now you might want to get it checked out. It could be an infection somewhere in your body.
