Bring about 2 inches of water to boil in a large pan. Slice potatoes into 1/2-inch pieces and place them in a steamer (metal or bamboo) that fits into the pan without letting the potatoes touch the boiling water. Steam them for 7 minutes. For extra flavor, steam garlic and onions with the potatoes.
Intervertebral disc degeneration is one of the most common mechanical causes of low back pain, and it occurs when the usually rubbery discs lose integrity as a normal process of aging. In a healthy back, intervertebral discs provide height and allow bending, flexion, and torsion of the lower back.
1 This can cause problems if they rub against nerves, particularly the sciatic nerve, or if they should leak caustic substances onto the nerve itself. This causes approximately 10% of all lower back pain problems.  In rare cases, tumors, pelvic infections and other situations can cause sciatica as well.
