My husband was diagnosed with viral meningitis 7 months ago. The virus is now gone but he still has a terrible headache. He has stopped taking Percoset ,(Dr. thought it was a rebound headache.) That was 13 days ago! Anyone have any ideas? He will have 3 or 4 good days then 7 or 8 really bad days. just keeps going and going around in a circle. He's driving me up the wall 8)
