Earlier i noticed the red spot on my leg and on my neck. is this a sign of the chickenpox, what to do?

2 red spots on your: Body probably isn't chicken pox. A rash from chickenpox often occurs first on trunk (chest/back) ; then moves to face ; then extremities. The rash becomes blisters that itch. Blisters usually have all transformed into scabs in about a week. There are usually around 100 to 300 lesions (more on adults than small children). The rash could spread to mouth, eyelids ; genitalia.
