I get severe sharp pains in the back right side of my head. They seem to come in waves, and are so painful I cannot move. My vision blurs and my whole neck and head tense. I also noticed that there is a small indenation in the area where I get the pain. It started a few years ago, but has become more prominent recently. I get headaches more frequently as well. I m a 25 y/o female. What am I dealing with? This sharp pain lasts between a few seconds to a few minutes.
