I have been diagnosed with ocular migraines. Mine are usually painless. They're usually "auras" like flashing zigzag pattern, flicking light (old movie reel) in a top portion of visual field, seeing through flame (you know when it really hot outside and the air is kinda wavy and a partial loss of visual field (it went grey like when the tv reception is bad, like snowy). That's the best way I can explain them. Now, I have also had pain when I move my eye. I still don't know what does that. It happens once in a while. Only last a couple of days. I take Ibuprofen and it usually helps.
