Your decsription tells that this is not chicken pox
They seems like petechiae
which result from many causes and prominent amongst them these days is reduced platelet count
due to dengue or malaria, if its spreading in your area.
Swollen glands can be a result of some infection... bacterial , viral and atypical infections like infectious mononucleosis
I would suggest you to gget tested and till then you can start yourself on Tab Doxycycline 100 mg twice daily for 5 days. Or till the results of your tests are available.
