Not likely. Kyphosis (scheuermann's disease) is a curving of the spine that causes a bowing or rounding of the back, which leads to a hunchback or slouching posture...Basically scoliosis of the thoracic spine. This does not cause night sweat! Severe kyphosis is a risk factor for pneumonia etcc...Which can cause night sweat, among other things. If you have night sweats, consult your doc. Good luck.
