Hi, It sounds like you are experiencing symptoms of opioid withdrawal, which can include restlessness, insomnia, and muscle spasms. Opioid withdrawal can be uncomfortable, but it is typically not life-threatening. To manage these symptoms, you may want to consider talking to your pain management doctor about a medication-assisted treatment plan, which may include a short course of medication to help ease the withdrawal symptoms as you continue to taper off the oxycodone. Additionally, some non-pharmacological strategies may help you manage these symptoms, such as exercise, stretching, deep breathing, and mindfulness meditation. You may also find it helpful to engage in activities that promote relaxation, such as taking a warm bath or reading a book before bedtime. It s difficult to predict how long your symptoms will last, as everyone s experience with opioid withdrawal is different. However, symptoms typically peak within the first few days of discontinuing opioid use and gradually subside over a week or two. It s important to work closely with your pain management doctor during this process to ensure that you are safely tapering off the medication and managing any withdrawal symptoms that may arise. They may also be able to provide additional support and resources to help you through this process. Take care. Hope I have answered your question. Let me know if I can assist you further.
