Muscle spasms are generally self-limited to 2-4 weeks in length, with corresponding muscle relaxant treatment options reflecting acute duration of use
Nonspecific, low back pain is a predominant manifestation of muscle spasm, and in
most cases, has no underlying cause
Nonpharmacologic treatment is first recommended for muscle spasm relief, followed by nonsteroidal anti-inflammatory drugs (e.g. aspirin, ibuprofen), muscle relaxants, and/or diazepam or botulinum toxin in refractory cases
