I occasionally have sharp, brief (scalp pains on the right side - they are intermittent and they sometime 'ping' me on their own, or if I touch my head (brush my hair etc.). When touching a sensitive spot repeatedly, the pain will stop and may move to another part of my scalp, front, middle or rear, always on the right side. Ibuprofen definitely helps. This is only occasional, but am now having a longer spell (3 days). What could this be?
