I have about 4 small blisters on my body, two on the arms, one on the back and one on the thigh,they don t itch , I ve pinched them open. Now they re only painful if I put pressure on that area. 2 days after the blisters started to appear I have fever , I don t know if both things are related. I took a paracetamol last night but after I woke up the fever is back.
