I had to visit the nurse on this last cruise.
I have a condition called Posterior reversable encepolopthy syndrome. When I filled out the paper work at the clinic I listed that as a pre existing conditon. The nurse had no clue what is is. She gave me some great advice that I want to pass along.
If you have a rare or unusual condition print off information on the condition and carry it with you so if you have an attack or flare up the dr can read it and can treat it. I thought it was great advice. My syndrome can be fatal if not treated if I have an attack. This is great advice I plan to follow
