3: If your walking pattern has changed
Cause: This might be a symptom of one of your discs slipping out of your vertebral column. A common indicator of this is when your gait is stooped and crooked (tending to one side), which happens because your spine is unable to bear weight on one side. The severe muscle weakness caused due to increased pressure on the nerves leads to muscle weakness and a condition called foot drop, which makes you drag your feet when you walk. Another reason could be sciatica or obesity.
Treatment: If you are going through severe pain, altered sensation in the legs, motor weakness, difficulty in walking with or without back pain then you must visit your doctor.
