Brief Answer: Follows. Detailed Answer: Dear Madam, Thank you for posting your query on XXXXXXX Well looking into your query I will like to tell you that you complain of red rash on foot and arm which is itchy . There can be many causes for this rash nothing can be said conclusively about this unless it is examined . But since it is itchy there is a possibilty that it could be allergic, or some drug induced rash .Even viral fevers can give such kind of rash. Possibilty of vasculitic rash is rare . I will advise you to see a doctor for this early as only after examination of rash any treatment can be advisable . Antiallergics like cetrizine and steroids may be beneficial to control the rash . Take care. Dr. Shruti
