I'm a 14 year old girl, I found about 12 to 14 bumps on my body, they do not itch. I have already had the chicken pox twice, should I be worried about this?

I . I doubt it is chicken pox since your body was "immunized" by having a prior infection. There are numerous other possibilities and it is hard to tell without a picture, but perhaps they could be warts or molluscum contagiosum. Another possibility would be acne or folliculitis which is also common in your age group. I would recommend you get evaluated by a dermatologist if these bumps don't resolve very soon.
