Top 9 Weakness of Both Legs Causes

  1. 1.Herniated (Slipped) Disk in the Lower Back

    The backbone, or spine, is made up of 26 bones called vertebrae. In between the bones are soft disks filled with a jelly-like substance. These disks cushion the vertebrae and keep them in place. Although people talk about a slipped disk, nothing actually slips out of place. The outer shell of the disk ruptures, and the jelly-like substance bulges out. It may be pressing on a nerve, which is what causes the pain.A slipped disk is more likely to happen due to strain on the back, such as during heavy lifting, and older individuals are at higher risk.

    For treatment of a slipped disk, you should consult with your primary care physician (PCP). Your doctor will perform a thorough physical examination to localize the slipped disk and rule out dangerous complications. Most people do not require surgery for a slipped disk. Treatment involves pain relief with an over-the-counter pain medication such as ibuprofen (Advil) and/or acetaminophen (Tylenol), using heat treatments, and keeping active. It is best to avoid sitting still for long periods. Walking or swimming may help as well.
