It is really a tricky thing when your child has chicken pox, but in this case you must not let your child scratch, because a scratch will easily leave a scar after the chicken pox breaks, and the scar will be more obvious. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. This is because chicken pox itself is a viral infection, and applying hormonal drugs will cause the spread of chicken pox herpes. If necessary, you can also take oral anti-allergy medication to stop the itching effect. Remember to never scratch these blisters with your hands, as this can cause scarring.
