After drinking nopalea , one full bottle I got a terible pain over my eyes, to the point I went to the hospital, mri, cat scan, nothing wrong there. Took some meds pain was less, but the next day out of the hospital the pain is back, but mostly in my right eye. Anybody have this experience?

You could be allergic to the juice, the dyes (if it's a brand which contains dyes), a preservative (if it's the kind that contains preservatives).

What did the Doctor say in the ER?
