hi. i have been having headaches daily for nearly 3 weeks now. have seen my gp who has prescribed zoltriptopram...this gets rid of the headache, but it comes back later. It seems to be focused around the right eye, but has been on the left too. my eyelid droops & my eye waters whilst the ache is present, then lifts, blurred vision goes once pills kick in. worried i have something grim. I have had my eyes tested too,& nothing wrong
