A lumbar sympathetic block is an injection of steroid medication and local anesthetic into or around your sympathetic nerves to help relieve lower back or leg pain. Sympathetic nerves are located on both sides of your spine, in your lower back.
Spinal cord stimulation uses a small device to deliver electrical pulses to the spinal cord, masking pain signals before they reach the brain. It helps people better manage their chronic pain and reduce their use of opioid medications.
DRG stimulation features two components that are surgically implanted: A pulse generator, which is placed beneath the skin in the buttocks or abdomen, and up to four leads. The leads are attached to the pulse generator and the tissue near the target treatment area. When activated, the leads send very small electrical impulses to the dorsal root ganglion, thereby blocking the pain stimulant.
