I'm familiar with the numbness and tingling in the hand one can get from hgh use. I've been on hgh for about 2 months now, 1st month = 2 ius/day, 2nd month onward 1.5iu's/day. For the last 3-4 weeks I wake up in the morning with extreme tightness in my tendons and muscle making it impossible to make a fist or touch my thumb to the tips of my pinky or ring finger(both hands) for about an hour. Once I get going the problem goes away. Has anyone else experienced this?
