Tramadol is a synthetic chemical compound that is used to treat pain and discomfort. It is normally an ingested medication that works centrally instead of locally. While it is used as a pain reliever, it is often not prescribed to handle very severe pain. Ideally, it is given for mid-level to mid-level severe pain. Given the wide range of pain thresholds it can handle, it is prescribed for quite a lengthy list of painful or uncomfortable conditions such as fibromyalgia, motor neurone disease, restless legs syndrome, rheumatoid arthritis, among many other conditions. In this respect, Tramadol is prescribed similar to pain reliever drug classes like codein.
