Has anyone had this? I was on holiday in Spain the start of June when this first happened. I didn't get my feet sunburnt. Came home and after about a week they healed up. Was just pottering around the house today looked down at my feet and had four large blister on my toes! Any help would be appreciated, I am seeing my rheumatologist in two weeks so I am going to mention this to him. I've taken some photos too in case I don't have blisters in two weeks time. A really strange one.
