Pain caused by musculoskeletal disorders and pain caused by damage to the
nervous system
may have different symptoms and are often not resolved, even with drug
treatment.

In rehabilitation pain treatment, pain is controlled by alleviating inflammation and
muscle stiffness through various physical therapy techniques
such as heat therapy, cold therapy, laser therapy, phototherapy, electrotherapy, and ultrasound
therapy,
as well as muscle reeducation and restoring lost physical functions.
