When I am dehydrated, I tend to get muscle cramps, particularly in the calf. After I started T, I had quite a bit of muscle growth, and I was having some cramps in my calves and also in places where I don't normally cramp. But I was hydrating regularly, so I guess my new muscle was just a bit delicate or something.
I had a bit of joint ache here and there, but mostly in my right ankle, where I have an old injury. My ankle is better than ever now.
I was under the impression that if your plates haven't fused yet, you can grow a bit on T. Seems to me that if androgens stopped people from growing taller, we would have an awful lot of short men in the world.
