Hello I have these small clear fluid filled blisters under my armpit. They burst spread and leave horrible looking sores. I ve been to the doctor the told me it was shingles and that there was nothing they could do and to let it run It s course. I m not sure its shingles because he also said most people complain of pain which I haven t had any pain but when applying rubbing alcohol. Also today it seemed to smell like rotten fish which also makes me think its not shingles as I don t think that is a symptom. Please help I need some answers!
