Not a seizure. This is not a seizure. It is probably in your scalp. This is a benign condition which can be handled in many ways. Depending on how long this lasts, a safe, inexpensive medicine can be helpful for this. Consider also if it is affected by moving your head.
Usually muscles. Usually specific tender spots on the scalp are due to contractions and spasm of the scalp muscles. These can often be helped with massage, relaxation, etc. If you have any more worrisome symptoms (blurry vision, dizziness, balance problems, etc) see a doctor asap.
