I have had a tension headache for two days, I used a heating pad on the back of my neck. Its gone now. But I noticed two small lumps right below my hairline on the back of my neck on the right side. I also have one on the left side below my hairline. Should I be worried?
Hi, Do not be worried. These are most likely to be sebaceous cysts which are harmless. They do not need any treatment if they remain small.  Chat Doctor.
