The wrist can hurt when on HGH . It did the same thing to me and I stuck it out and now there's no more pain. It lasted about 6 months but only the left wrist. If that's the pain with out gain there talking about it's worth it. Some say carple tunnel others say it's bone growth and I say it's just your body getting used to growing again. You can take gloucosimine or glutamine if it hurts real bad.
GH can cause sodium retention and often times the linings the nerves pass through (especially in the wrists) become tight and it applies pressure on the nerves and causes numbness and pain, cut your dosage.
