For now my advice would be to use tea tree oil or something similar on them a couple times a day, it'll help to dry them out. Not over washing yourself, as this can cause irritation. Keeping your hair off your neck/shoulders if it's long can help too.

You might be able to get fucidin OTC, I'm not totally sure. Ask the pharmacist if they can help. (Don't get fucidin mixed up with fucidin H).
