“Minimally invasive” simply means that the majority of the procedures we perform (with few exceptions) are done percutaneously or through the skin. Percutaneous procedures involve the introduction of very small needles or needle-like instruments, and do not require stitches afterwards. This approach means that the risk of infection and complications, while still present, is minimized.It can be normal to have pain after an injection. Every person responds differently; some patients feel worse before they feel better, others feel better right away. If pain persists, apply icepacks for 10-15 minutes every 4-6 hours. DO NOT use a heating pad for 3-4 days after your injection.Call the office if you experience any of the following symptoms: fever, persistent headache, bowel/bladder issues, or new onset weakness.
