I topped out at just 6’1” but recall the pain of a growth spurt in junior high. For me it felt more like bone pain for the most part but there was a vague ache in soft tissue elsewhere as well. I can’t say I was exactly racked with pain but it was pretty uncomfortable for the better part of a year.
I think the bone pain is a result of them being under constant compression from the too-slowly stretching tendons. Joints especially bothered my son, which would make sense.
