question: I noticed I had a knot on my head about the size of a quarter. It is hard and a little sore to touch. I thought I must have hit my head but could not remember. Lol. I woke up during the night with a headache and when I put my hand to my forehead I felt about five lumps. All skin color, hard and various sizes but all on the same side as the lump on my head. It has been a few days and no change. One week before I went to urgent care with a sore throat and swollen lump nodes and was given an antibodic. What is going on.
