The appearance of clear blisters after a flea bite is usually caused by an allergic reaction of the skin to proteins in flea saliva. This allergic reaction causes local skin inflammation and edema, which in turn leads to the formation of clear blisters.
If a flea bite results in clear blisters, it may be accompanied by local redness, itching, and mild pain. These symptoms usually appear within hours of the bite and may last for several days. It's important to note that if the blisters rupture, secondary infection may occur, leading to increased redness, swelling, and pain, and even purulent discharge.
Key precautions: If you experience widespread blisters, severe itching, pain, or symptoms such as fever or swollen lymph nodes, seek medical attention immediately. Avoid squeezing the blisters yourself to prevent secondary infections. Individual symptoms vary, so it is recommended to seek professional medical diagnosis and treatment if you experience significant discomfort.
