I am 28 and I see one or more circular multicolored shape that flashes, even with my eyes closed. This has been since 3 months. Eye tests are all normal. The features are as follows:
1. They last for maximum 2 minutes and happen more than 2 times a day.
2. They get intensified by exertion and almost always happen when I am walking fast.
3. They are not followed by a headache.
4. They are always at the same location, a little to the left from the centre of my visual field.
The neurologists I went to ruled out migraine and asked for EEG. I had EEG twice and both came normal. I am still undiagnosed and don't know what to do or if I should do something or let it be.... if anyone experiences the same, please guide me.
