I've been getting blisters that are itchy. i'm starting to believe it's not an insect. i now have multiple blisters on 1 spot. on feet and leg.

Atopic vs allergic: The best way to sort this out is to find out what caused the blistering and itchiness . Suggest a dermatologist and/or allergist to figure out what is the underlying cause. A biopsy of the blister tissue and fluid may or may not give you an answer, but you need a direct examination ASAP, this should help to diagnose this condition
