Some redness at the skin test site is expected. The site may itch, but it is important that you do not scratch it, since this may cause redness or swelling that could make it hard to read the skin test. If itching is a problem, put a cold washcloth on the site and then dry it.
A strong positive reaction may cause mild pain. Talk to your doctor if you have:
- A fever.
- Swelling in your arm.
- Swollen lymph nodes in your armpit.
