Ive woken up this morning with my skin bright red like it's sunburnt but it's not. I've not been in any sun. My skin has got a slight burning sensation like sunburn also. My joints are aching too which i have never experienced before. My knee's are the worse. It's not a painful ache, more of a tight uncomfortable ache. As it's saturday my dr's are closed and dont really want to be waiting and wasting hospital time if i dont need to. Has anyone ever experienced anything like this before? Tia sx
