My doctor says I have tinea pedis with id reaction; meaning that I have athlete's foot and the fungus got into my bloodstream and caused a reaction on my hands and is now spreading to my arms. The doctor gave my Lamisil tablets (to take by moth) and Allegra for the itchiness and some lotion. My hands are covered with tiny blisters and are swelling up like marshmellows. It seems to be worsening and is now spreading to my arms. It is driving me crazy! What else can I do?
