I face sharp pain in the back of my head, I would describe the pain as a sharp wound. It keeps throbbing like he'll and I encounter headaches for for days and I think it's not normal at all. I did consultant a doctor before regarding this but I didn't know that I felt headache which weren't severe but ik did present. This is really creating problems when I try to focus on things while studying as I can't stare at my book for long and the constant pain which is mild but is still there...the pain is like a ring which continues from the back of my head to my forehead. I'm I sounding crazy? But that's what I'm experiencing!
