When fleas bite humans, inflammatory bumps and blisters may occur.
Blisters on an uninflamed base on the legs and feet are typical. Lesions are usually below the knee as the flea can't jump very high.
Treating the infestation is key. Popping any blisters (but not removing the roof) is recommended. A potent topical steroid BID x 3-5 days may be given.
Notice the key characteristic localization about the ankles.
