Low back pain can be caused by tumors, either benign or malignant, that originate in the bone of the spine or pelvis and spinal cord (primary tumors) and those which originate elsewhere and spread to these areas (metastatic tumors). Symptoms range from localized pain to radiating severe pain and loss of nerve and muscle function (even incontinence of urine and stool) depending on whether or not the tumors affect the nervous tissue. Tumors of these areas are detected using imaging tests, such as plain X-rays, nuclear bone scanning, and CAT and MRI scanning.

Men and women are equally affected by low back pain, which can range in intensity from a dull, constant ache to a sudden, sharp sensation that leaves the person incapacitated. Pain can begin abruptly as a result of an accident or by lifting something heavy, or it can develop over time due to age-related changes of the spine. Sedentary lifestyles also can set the stage for low back pain, especially when a weekday routine of getting too little exercise is punctuated by strenuous weekend workout.
Marvelously progressive, concise, and cogent guidelines for physicians on the treatment of low back pain. These guidelines almost entirely “get it right” in my opinion, and are completely consistent with recommendations I’ve been making for years on PainScience.com. They are particularly to be praised for strongly discouraging physicians from ordering imaging tests only “for patients with low back pain when severe or progressive neurologic deficits are present or when serious underlying conditions are suspected.”
The hip flexors are the group of muscles that allow you to lift your knees toward your chest and bend forward from the hips. What is collectively referred to as the hip flexors is actually a group of muscles that includes the iliopsoas, the thigh muscles (rectus femoris, Sartorius and tensor fasciae latae), and the inner thigh muscles (adductor longus and brevis, pectineus and gracilis).
The hip flexors play an important role in everyday mobility and exercise. Involved in pulling the knee toward the hip, most movements either directly or indirectly use the hip flexors. That’s why even the slightest injury can cause great discomfort. Learn how you can recover from a hip flexor injury, and what precautions can be taken to avoid them.![]()
