Dude welcome to the club. That is the normal although unpleasant side effect of HGH. Its worse for some of us than other. I was in the same boat as you walking around at night in agony http://forums.steroid.com/showthread.php?t=259153 . I ended up stopping for a while it was so bad. Best thing to do is to back the dose down to 2IU until it gets better, if not go down to 1 IU or off completely for a while if that doesnt work
