Muscle relaxants like Pain o Soma 500 (carisoprodol) act by preventing the transmission of pain signals from the nerves to the brain. It is generally agreed that aches and pains felt in the muscles, bones, ligaments, and tendons constitute musculoskeletal discomfort. Injuries can range from being temporary, like sprains and strains, to being permanent, such those that cause permanent disability or significant limitations in daily life. People with musculoskeletal pain frequently report feeling uncomfortable all throughout their body. They report that their muscles are sore and exhausted from the exertion. Sometimes muscles can twitch or burn. Soma, like other medications in the skeletal muscle relaxant family, works best when taken under medical supervision.
