The use of oral or injectable medications that relieve pain when lying still or sitting still. Conventional oral medications such as paracetamol, anti-inflammatory pain relievers or anticonvulsants have no effect on pain relief when the patient turns or moves, so they do not help return the patient to a normal rhythm of life. Sometimes the use of anticonvulsant pain relievers makes the patient feel drowsy, tired, weak, and do not want to do anything all day.

Pain and difficulty moving the back due to uneven muscle spasms on both sides of the spine cause spinal twisting like the image of a bicycle wheel being "turned to the rim" according to folklore. Therefore, the general principle of pain treatment intervention is to quickly relax the low back muscles to help create a new balance of the back mass on both sides of the low lumbar spine to help relax, thereby reducing muscle pain. and easier to maneuver.
An injection that blocks the somatosensory nerve branch of the dorsal muscle mass itself emanating from the dorsal spinal nerve root that provides immediate pain relief is called an erector spinae plane block injection (Erector Spinae). Plane Block, ESPB)
