Did you report the reaction to the first doctor? It's important to always report these reactions. For this drug specifically, you can even go to the web site and use a contact us form to report an 'adverse event' (select that option from the drop down menu)- http://www.valeant.com/about/contact-us
Based off a quick google search, it sounds like infection caused by fungus may also be a common side effect. The Triamcinolone cream, actually would potentially make that worse. Tacrolimus is more for an eczema rash- so it might be that you need to be checked for a fungal infection instead. Head back to the doctor, and let them know that it's not working- hope you feel better soon!
