Hi my husband had an infection on the top of his left foot we thought it might be caused from a spider bite he would scratch it till it bled now he has a lot of little red bumps like a rash that are pimple size with pus on both legs, arms, hands,fingers, back and chest. he has never had chickenpox. his foot is red and he has soaked it in Epsom salt a couple days it looks to be drying up but his legs,arms,hands,fingers look really bad. sometimes the pimple will ooz and pop if he bumps it. he has a lot of itching also. we don t know where the rash came from and wonder also if its contagious he has had it a week now and I have no symptoms or signs of what he has.
