Thank you ! [/INST] Hello,Welcome to HCM, The symptoms of chicken pox is very severe in adults as compared to children, the complications are more in adults as compared to the children.Chicken pox is a disease which affects all the organs in the body including genitals and it produces very bad symptoms like severe plemorphic rashes with excruciating pain.It is a self limiting disease and one attack will give lifelong immunity, the antiviral drugs like acyclovir will not cure the disease but it will prevents the multiplication of the virus and prevents the complications.The rashes will subside in the same order of the appearance, if there is any pus better to take a course of oral antibiotics along with the antiviral drugs. The symptoms will come down in 10-15 days after the appearance of the rashes.Thank you. </s>
