Yesterday, I had a muscle cramp on my left leg while coming out from the swimming pool. The pain was very intense for 5 minutes and the muscle started to get into its place. Then I felt like my body and mind is going to give up, I started seeing everything too bright. The blue water, the trees, the building nearby, everything too white and too bright. I can't see anybody swimming down there. I started thinking like this may be the end of everything. And It remained for 10 minutes and then it started getting back to the normal.
Now I have no problem with my eyes and the leg; like nothing happened. But just curious what was the reason of such bright vision. Hope to hear from an expert :)
