Imaging is indicated when there are red flags, ongoing neurological symptoms that do not resolve, or ongoing or worsening pain.[5] In particular, early use of imaging (either MRI or CT) is recommended for suspected cancer, infection, or cauda equina syndrome.[5] MRI is slightly better than CT for identifying disc disease; the two technologies are equally useful for diagnosing spinal stenosis.[5] Only a few physical diagnostic tests are helpful.[5] The straight leg raise test is almost always positive in those with disc herniation.[5] Lumbar provocative discography may be useful to identify a specific disc causing pain in those with chronic high levels of low back pain.[41] Similarly, therapeutic procedures such as nerve blocks can be used to determine a specific source of pain.[5] Some evidence supports the use of facet joint injections, transforminal epidural injections and sacroilliac injections as diagnostic tests.[5] Most other physical tests, such as evaluating for scoliosis, muscle weakness or wasting, and impaired reflexes, are of little use.[5] 
To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened. “Because we spend so much of our time in a seated position with the hip flexed, the hip flexor has the potential to shorten up. Then, when you are in a hurry because you are running to catch a bus or a plane, or you trip and fall, the muscle could become stretched. Here’s this stiff, brittle muscle that all of a sudden gets extended, and you could set yourself up for strain or some hip flexor pain.” Click Here to Learn Unlock Hip Flexors
