Where do doctor's give the injection for spinal anesthesia?

Doctors administer spinal anesthesia by injecting the anesthetic into the subarachnoid space, which is located in the lower back. This is typically done between the L3-L4 or L4-L5 vertebrae to avoid damaging the spinal cord. The injection is performed using a thin needle, allowing the anesthetic to flow around the spinal nerves and provide effective pain relief during surgical procedures.
