Acne breakout after chicken pox. Me?

I never had any  acne or breakouts in my life .But after chicken pox,I started to breakout severely in a larger number  all over my face,shoulders and my back.I had chicken pox 3 years ago and my face was never affected by it luckily at that time so there was no problem at that time .But  after that someday  my face suffers acne and I tried many doctors , many  prescribed  creams by them and tablets but it didnt make any difference .Its been 3-4years and still i am suffering. I thought it will decrease by time because i never had pimples or acne before that and I dont use any  oily creams or make up.But it gives no signs of going away.As soon as the previous inflammation goes away other one will be emerging. I am fed up as there is nothing else I can do.Is there any solution to this acne problem after chicken pox? Is this because my chicken pox was not properly treated 3 years ago? My face is a mess right now. please help me?
