I can relate (all too well, as you know)! I too am allergic to neosporin (well, actually the neomycin in the neosporin) - are you allergic to mango as well (the oil in the skin of the mango produces the same rash that the neomycin does)?

Take care, and when the scabs start to itch (which, they will in a few days), resist the urge to scratch! Here's to a speedy recovery.
