I have a really bad sunburn on my feet. It all started 6 weeks ago, after 2 hours in the sun everything seemed fine. Then about three days later a sunburn started to appear on just my feet. The burns continued to get worse over the next week resulting in huge blisters. I went to several doctors ending up at the dermatologist. I was given steroids and ointment. It was classified as hypersensitive delayed reaction. Now it has been between 6 and 7 weeks and new blisters and burns have appeared on my feet and no where else. They believe in the original diagnosis but did a biopsy anyway. I have been given more steroids and Topicort spray. Since last night the burns on my toes have turned a deep purple and seem very dry looking. My feet are incredibly swollen and I have never had that problem before. I am wondering if this is something I should just wait until the office opens on Tuesday or should I get this checked sooner at the emergency room? Just nervous never had a burn that has lasted this long before.
