Hi Dr. Dyoti,
This isn't your fault, given the information I gave you. But the pain got much worse and spread, to bladder and colon, and I became feverish. Finally called the doctor who diagnosed a flare up of Sjogrens due to a diverticular infection.
He advised increasing the steroids but not to take antibiotics. The pain became worse and I developed pemphigoid vasculitis. Another doctor put me on to anti-biotics which cleared the infection. And I'm gradually reducing the steroids as the rash begins to fade.
But thank you for your help. At least you treated my request seriously!
