I have a painful, itching rash on my face, lips, hands, arms, and back. I have been to dermatoligists and allergist with no answers. I did use a prescribed lip salve (Desonide Ointment) and it seemed to make the rash worse, especially on my face. I quit using this 11 days ago but have not seen any improvement. My doctor said I am anemic and gave me a B12 shot @ 3 weeks ago. I have been Anemic for several months. Any suggestions?
