No: Most back pain, even severe, can be managed at home and clinic by an experienced physician. Rest, medication, activity specific to your injury and some preventative care like no heavy lifting, twisting, jarring activities or vacuuming, are usually helpful. For walking difficulty and weakness, physical therapy may be needed. At your age, you may start with a chiropractor, then a md/do.
