I've had chickenpox for the last few days, I got a fever on Wednesday and felt unwell in myself. I had a few spots but didn't think it was chickenpox, until Thursday when I was covered in spots. I have been unwell everyday and new spots keep appearing while the original ones have started to scab. I feel really lethargic, have a bad headaches, a severe sore throat and an upset stomach, making me not want to eat. I don't know if I need to go to the doctors because I know it can be severe in adults. What do you think?
