What to tell us about your symptoms

Bites and stings may cause itching, pain, redness or swelling. The skin’s appearance alone does not reliably identify the insect or prove that there is an infection.

What the video visit can help with

Show the area in good light and explain when it happened, how it has changed and whether you have symptoms elsewhere. Mention previous serious reactions and any travel or known tick exposure.

When an examination or testing may be needed

An in-person examination may be needed when swelling, pain or illness is getting worse. The visit should help determine that need, not label an uncertain bite from a photograph.

Discussing treatment

For an appropriate concern, discuss symptom relief and whether further treatment is needed. Any prescription depends on the assessment rather than an assumption that every swollen bite needs an antibiotic.

When to get care in person

Trouble breathing, throat swelling, fainting or a widespread severe reaction after a sting needs emergency help. Seek prompt care for worsening illness, spreading skin changes or significant pain.

Before your visit

Keep track of when the bite was noticed and which products you have applied. A clear timeline and current view are useful even when you did not see what bit you.

Questions about this care

Can you tell what bit me from a photo?
