Hi! I ve had these rashes on my arms and legs and at the back for over 3 weeks now. My blood test reveals a normal CBC with a slightly high RBCs, negative in ASO, normal CRP, and 42mm/hr ESR. Also, I m having joint pains, I can barely walk. I also experienced fever (once) and chest pains. I also had rashes in the face once but disappeared in the morning. What should I do :(
