In the musculoskeletal part of the body, it’s not uncommon for a problem in one area to refer pain to another area nearby. Usually the nerve supplying the problem area also controls the site of the referred pain. Because the nerve affects more than one body part, messages via the nervous system don’t always get interpreted correctly.
Doctors and therapists know that when a patient presents with pain in any of the joints that they must consider the joint above and the joint below the painful one as a possible source of referred pain. In the case of the hip, this means checking the low back area and the knee as possible sources of the real problem.
Press-up (extension) exercises are often used in people with disc-related or nonspecific low back pain. Nonspecific means the cause of the problem is unknown. In many cases, the patient history and results of some simple screening tests point to the real problem area.
Press-ups to improve lumbar extension often reduce low back pain. These exercises can also eliminate hip pain when the true cause of the pain is coming from the low back area.
