I am aged 21, female. I am suffering from headache since last 4 or 5 years. That is severe pain at back of head. It happens throughout whole day but it does not happen continuously and not on regular basis. It starts then stops for few hours or minutes again it continues until I fall asleep. Sometimes, I feel like shock in my head and that stays for 1 to 5 seconds. During bike riding or even when I am on car, on uneven road I feel like thrust in my head. Here it is to be noted that I have no any kind of soreness in my head and never got hurt on my head in lifetime .city scan, mri has been performed under doctor's observation. One doctor said it's psychiatric problem, another said I have sinus related complications. Many medicines and treatment have been consumed and taken respectively but with no result. What can we do? Which doctor do you prefer? What might be the real reason behind this? P.s. I have family history of meningitis.
