Anyone else experience bright light trace (bit like foetal monitor trace or ECG trace)which passes across their vision. Also get patches of very blurred grey where I don't feel like am seeing anything. This been going on for a while (more than a year) but only happens occasionally and worse when tired and do have history of migraine. Am reluctant going to GP as unless your leg is hanging off will be made to see nurse and am clically obese so just know that will be what they blame it on. My blood pressure is high end of normal but doesn't need medication. Have almost lost 2 stone though so may be brave enough to go sometime. Anyone have any ideas ?
