Ringworm - Complications 

The most common complication of ringworm is that the infection spreads from one area of your body to another.

You can stop this happening by being careful about your personal hygiene. Read more about how to stop ringworm from spreading.

Sometimes, if ringworm leaves the skin irritated or broken it can lead to other bacterial infections, which may need treatment with antibiotics.

If your immune system doesn't work properly, for example, if you have HIV or you've recently had chemotherapy treatment, infections are more likely to spread.

With scalp ringworm, there is a risk of permanent scarring and bald patches after treatment, but this is rare.
