There's definitely a correlation between either remicade/prednisone and sensitivity to the sun. I want to say it is the prednisone. I am down to 30mg. Love to lay out in the sun. Can only do so for 45min max every couple days because I have been burning so bad. Can't wait to be off the pred. Prior to the pred I could spend hours at the pool/beach and rarely ever burned. I hope your son does alright on the boat.
