Azarga

I just started Azarga 2 weeks ago, and I can hardly stand it.  My eyelids are red and puffy, and by the end of the day I want to scratch my eyeballs out they itch so much.  I read one post in which someone said the symptoms disappeared after a month.  I'm not sure I can stand it that long.  My doctor doesn't seem too concerned.  I'm not sure I can live like this.  Any advice?
