Answer 1

Back Pain and Stiffness; kind of relation to Hunchback?

Step-by-step explanation:

It happens when we have poor posture; positioning our arms & shoulders not how we normally position them - it can also happen when carrying heavy stuff or slouching.

The ligaments and muscles that support the vertebrae can extend as a result of poor posture in childhood, such as leaning back in seats and carrying heavy backpacks. Kyphosis occurs when the thoracic vertebrae are pulled out of their usual position.
