If you start off with conservative doses like 1iu ED and titrate up slowly over the course of a couple of months, you can avoid all side effects entirely, including bloat, carpal tunnel and joint pain.
I have never personally had puffy face when just using HGH, I would suggest that you start off with a lower dose then what you actually want to use, and slowly build up to your prime dose.
These slower incriments will help to lower any discomfort and additional water bloat one sometimes does experience with HGH.
Also make sure that you congest more water then you currently do while useing.
