Muscle spasm

Muscle spasms are involuntary contractions that can cause sharp, cramping pain and stiffness.

They often occur after injury, overuse or as a protective response to spinal or joint pain. While they may serve as short-term protection, persistent spasms can worsen pain and reduce mobility. Treatments include physical therapy, heat, massage and sometimes muscle relaxants. In chronic pain, addressing underlying causes — such as nerve irritation or poor biomechanics — is crucial to long-term relief.
