Hi, I have been to many doctors and none would believe me until I showed. My eyes turn all black after I cry, I dont mean the skin or around the eye, the eye itself turns black. When I cry i feel a really strong pain like being stabbed on my eyes and then I start seeing a red line that crosses my eye from one corner to the other... then sometimes they turn black other times they dont... I understand if you dont believe me... other doctors also wouldnt until I showed... all I'm asking is for a bit of your attention and if you can help me knowing whats wrong with me... please help me... I also suffer from tachycardia.. so my theory is that the increase on the blood pressure around my eyes when i cry makes them turn black. Thanks for reading.
