Sounds like you have got some pretty sound advice already. With respect to the original question, your dosage of GH should be fine ... I doubt it will aid much more to increase it now.
With all back injuries, it is all a matter of getting those strained muscles to relax again and then giving them a break for a few days. If you have anything like flexeril or soma, taking that for a few days while applying heat and resting it will usually get you on your way a bit faster, but it is really just a matter of resting it, then afterward gently getting some stretching and gentle movement going back into it.
Best of luck to you. I can really sympathize ... I have episodes of similar problems. I have to say in general that while the body is a amazing thing, the aging body and the aging process really stinks!
