Tramadol is a medication that was originally designed as an analgesic for pain relief. It has since been used for other purposes such as treating migraines and neuropathic pain. What makes this opioid interesting is that it has a less significant side effect profile than opioids like morphine and oxycodone. This means that if you are taking tramadol, you may be more prone to develop an addiction because you don't experience many of the common side effects like drowsiness, nausea, and constipation.
