A small lumbar support can help prevent soft tissue injury by keeping your back in the proper position during activities such as heavy lifting and repetitive twisting or bending. When wearing a lumbar support, remember to bend and lift properly, and do not try to lift or carry more than you would normally. Though these techniques can help prevent back problems, it is inevitable that some people will still experience muscle strain. Pain can be severe in the days immediately following a back strain but will diminish as the injury heals. Applying heat to the area can also help relieve pain and relax the muscles.
Immobility is one of the worst things for back strain.
Mild activities like stretching and walking promote healing by increasing blood flow to the injured tissue and keeping muscles flexible. You can increase the frequency and intensity of activity as you heal. Call your doctor if necessary. If the symptoms do not diminish, contact your doctor. A severe strain may require a prescription-strength pain reliever or physical therapy.
