... treatment? I have been on recombinant HGH replacement for approximately two months. The dose was decreased when I had quite a few aches and pains. I still have some aches and pains and numbness in my right hand and forearm but a new symptom I have had on and off for the last three or four days a trembling throughout my whole body. It only lasts about 30 seconds but it is troubling to me as I have not seen it listed as a possible side effect of HGH treatment. Has anyone else had this experience of trembling?
