Most people will experience back pain at some point in their life. Back pain can be caused by many different things, including accidents, muscle strains, sports injuries, and lifestyle factors (weight, smoking, etc.).

Symptoms of low and mid back pain include:

  • Persistent aching or stiffness along the spine
  • Sharp, localized pain in the mid or lower back — especially after lifting heavy objects or engaging in other strenuous activity.
  • Chronic ache in the middle or lower back, especially after sitting or standing for extended periods
  • Back pain that radiates from the low back to the buttock, down the back of the thigh, and into the calf and toes
  • Inability to stand straight without having severe muscle spasms in the low back

You should make an appointment if:

  • You feel numbness, tingling, or weakness in your arms or legs, which may signal damage to the spinal cord.
  • The pain in your back extends downward along the back of the leg.
  • The pain increases when you cough or bend forward at the waist.
  • The pain is accompanied by fever, burning during urination, or strong-smelling urine, which can indicate an infection.
  • You begin to have problems controlling your bowels or bladder.
