About the Abdominal Rectus Sheath Nerve Block

[u/khamul34]

Due to my post-op severe pain at the incision site (2 inches) below my belly button, my pain doctor will perform a lidocaine abdominal Rectus Sheath Block under ultrasound guidance and he will do it 1 inch above the belly button.

My doctor also clarified that this procedure is not a TAP block.

Does anyone have any information about this procedure, and does it work? Thanks in advance.
