Welcome to HCM
It is really difficult time but you have already suffered chicken pox
last month,now is the time of recovery, let them heal naturally as putting nails to scar mark may make them worse.
I hope you must have been treated for the chicken pox,if scar mark are there just consult a Dermatologist
medicine like cetrazine will help to reduce itching.
As you are Model let me inform you that a simple Preventive Vaccine
is available for this diesase so if any one who has not suffered chicken pox can take this vaccine and this disease will be prevented.
not in your case.
Good Luck to You
