What could be the reason for headaches despite a normal MRI?

Hello,

Welcome to icliniq.com. Headache with sudden onset and the worst headache of life need evaluation. Since your magnetic resonance imaging (MRI) brain is normal, it is reassuring. One thing that still needs to evaluate is, has there been any change in your vision, how is your fundus (eye) examination (to make sure there is no increased intracranial pressure). If all these tests are normal, then you might be suffering from status migraine. Fioricet should be avoided as this may cause dependence. Things that would help, 1. Emergency room (ER) visit for migraine cocktail for headache relief. 2. Water intake two liters per day. 3. Exercise daily. 4. A good sleep of at least five to six hours. 5. Preventive medications like Riboflavin 100 mg oral daily or Magnesium oxide 400 mg oral daily (trial for a month). 6. See a neurologist for detail evaluation. Investigations to be done is eye examination (fundoscopy). Treatment plan include migraine cocktail if secondary Headache is ruled out.
