Pain O Soma is a brand name for the medication containing the active ingredient carisoprodol. It's a centrally acting skeletal muscle relaxant used to relieve acute musculoskeletal pain and discomfort. Pain O Soma works by blocking pain sensations between the nerves and the brain, providing relief from muscle spasms and tension. It's typically prescribed for short-term use, often in combination with rest, physical therapy, and other treatments. Like any medication, Pain O Soma may cause side effects, and it's important to use it only as prescribed by a healthcare professional.
