Retrospectively, 4 CT signs have been highlighted as follows (Table 1): fat infiltration in front of the sacroiliac joint in 86% of the cases, anterior bulging capsule in 43% of the cases, piriformis muscle swelling in 71% of the cases, and iliac muscle swelling in 71% of the cases (Figure 1, 2).
Massaging the piriformis muscle located here can help it relax, removing pressure on your sciatic nerve.
The programs include MyoFascial Release, relief from Migraine, Trigger Finger Piriformis Syndrome, Cramps and Back Pain.
The associated Low back pain can have multiple differential diagnosis such as Radiculopathy, Prolapsed disc, lateral canal stenosis, Sacroiliac joint dysfunction, myofascial pain syndrome, piriformis syndrome and so on.
In the differential diagnosis, bladder syndrome, vulvodynia, levator myalgia, piriformis syndrome, coxodynia, cauda equina syndrome, neuralgias and inflammation of other nerves such as obturator, genitofemoral, or ilioinguinal nerves should be considered.

The anatomy of the sciatic nerve has been well described in literature.[4-8] It arises from the anterior divisions of L4 through S3 and the posterior divisions of L4 through S2 forming the tibial and peroneal branches, respectively.[7] These nerve fibers coalesce to enter the gluteal region through the greater sciatic foramen below the piriformis muscle coursing inferiorly beneath the biceps femoris muscle in the thigh.[8] Although the tibial and peroneal branches are separate and distinct[1,5] along the entire length of the nerve, these are technically formed as the sciatic nerve bifurcates which is usually in the distal thigh.
It leaves the pelvis through the inferior part of the greater sciatic foramen and enters the gluteal region below the piriformis muscle.
