I have tried many different medications including anti depressants, beta blockers and am now on anti epileptics, none have helped. Other
symptoms I have are - my left pupil is slightly larger than my right, my left eye twitches when reading, extreme pain when looking upwards which increases my headache, double vision when reading, blurred vision, itchy and irritated eyes.
I have had an eye test and the optician said I had slight astigmatism.
