The onset of chickenpox would primarily be fever, followed by the appearance of vesicle rash. Vesicles are blister-like small pocket containing clear liquid. This occurs because of infection to Varicella Zoster Virus (causative agent for chickenpox). These vesicles continues to spread for an incubation period of 10-21 days. The vesicle skin rashes are seen mainly on the face and the body, with lesser occurrence on the hands and feet.
So what’s another torture in having the disease other than looking so terrifyingly not you? Well, these vesicles that I mentioned are so itchy that they will make you scratch them ’til they burst. But that won’t be a very wise thing for you to do. Scratching these would only make it more painful and uncomfortably itchy. It would also probably lead you to a much greater risk for skin infection due to those open sores you’ve caused from scratching. Another point here is that once you’ve burst those vesicles, it will indeed disappear temporarily but then new vesicles would still appear within the incubation period. And what’s worst is that after the disease process, once all of the vesicles have crusted no more lesions appear, those vesicles that you have dumbly scratched would form into scars. These scars are usually either pitted, keloidal, or would depend on the extent of the scratch.
So along with having a lifetime immunity from chicken pox, you’ll also have a long time scar. But of course, nothing much to worry about scars if you have the money to splurge on dermatological treatments. Don’t get so assured of these treatments though, because not all types of scars could be treated. Just to be safe, if you are having these vesicular skin rashes it would be better to try as hell to put your claws off it.
