Perform some additional tests for piriformis syndrome which may mimick low back pain or sciatica. Also ckeck for tranchanteric birsitis. Have a look over the tests for piriformis syndrome.

Pace test: Reproduction of sciatica type pain with weakness is noted by resisted abduction/external rotation (Pace test).

Freiberg test: The Freiberg test is another diagnostic sign that elicits pain upon forced internal rotation of the extended thigh.

Beatty maneuver: The Beatty maneuver reproduces buttock pain by selectively contracting the piriformis muscle.
