What are the side effects/risks of taking epidural injections to treat the pain?
Although injecting steroids into a closed space (as is done with epidural injections) limits the amount of steroids reaching the systemic circulation, there still may be some side effects. The most common side effects include water retention, weight gain, and high blood pressure. Epidural steroids are used cautiously in diabetic patients because the blood sugar levels of these patients may be more difficult to control. Fortunately, major complications associated with epidural steroids, such as paralysis or nerve damage, are extremely rare. There is a small risk of infection and spinal fluid leakage. Blood thinners such as coumadin should be stopped before steroid injections to reduce the risk of epidural hematoma.
