shingles for us was a wave of spots on one side from about tummy button round to the centre of the back, all together
they ended up looking like chicken pox blisters but bigger and more elongated, and really painful
I don't know about scbu.. I suppose I would but I don't know if one ought
I hope it's not shingles
I THINK that shingles is only contagious if in contact with the actual varicella stuff inside the blister and not like chicken pox
but you'd have to check that
hoep it's just a heat rash
