Low back pain is common & acute soft tissue spasms are oft implicated. Heat can loosen soft tissue spasm as can massage. Topical patches of Lidocaine & Solanpas work well. Injections of Dextrose by Dr’s have long been used with great safety & done in the office. Dr. specialists called Physiatrists are especially skilled at treating ongoing back pain.
