Just got back from the Wonder Eastern yesterday which was awesome. But when I woke up yesterday I had a welt on my leg with a blister (bumpy like) in the middle of some sort. We went to Castaway Cay on Friday and I don't remember feeling it than. But it is very itchy and red not sure what it can be from. Has anyone had this from previous cruises or have any ideas as to what it might be from and what I can put on it?
