Welcome and thanks for posting your query to HCM.
After reading your query let me very clearly tell you that you have hte problem of "Steroid Abuse". This means inadvertent and injudicious use of steroids
and other steroids.
The steroids have made your skin thin and atrophied because of which you are developing red rash
as well as light brown rashes with itching.
It is a very problematic state and you need to meet a proper dermatologist
who can wean off the side effects of steroids. It will be taking mutiple of months for the same so kindly have good follow up with great patience with your treating doctor.
With good health wishes
Dr. Sanjay Kumar Kanodia
