i am allergic to sulfa & years ago was switched from dyazide to procardia xl, diovan & spironolacton

I am now 91 years old have been allergic to sulfa drugs since a child. After taking dyazide for 25+ years I developed a severe redness on my forehead which itches and also feels like a constant fever.  A dermatologist said dyazide was the cause and my cardiologist switched me to diovan, spironolactone and procardia xl eight years ago.  Now 8 years later the redness is back with the same symptoms.  The doctors ruled out lupus with biopsy, etc. and the steroids offered provide only temporary relief.  Could it be that some drug interaction is the cause of the problem again?  I do not take Diovan HCT which has sulfa in it, but do not know if the combination of diovan, spironolactone and procardia xl causes the redness of not.
