My son has had a headache now for 3 years and it's there is no relief from any medication. Physical exertion makes it worse so he hasn't worked for 3 years. he was a very fit young man with lots of sporting achievements and now has next to no life.He has had 6 mri' s, 5 CT's, 2 lumber punctures and lots of tests including blood.Any help would be useful we have even resorted to a psychic.
