Chill it. Ice is best in the first 24 to 48 hours after an injury because it reduces inflammation, says E. Anne Reicherter, PhD, PT, DPT, associate professor of Physical Therapy at the University of Maryland School of Medicine. “Even though the warmth feels good because it helps cover up the pain and it does help relax the muscles, the heat actually inflames the inflammatory processes,” she says. After 48 hours, you can switch to heat if you prefer. Whether you use heat or ice — take it off after about 20 minutes to give your skin a rest. If pain persists, talk with a doctor.
Keep moving. “Our spines are like the rest of our body — they’re meant to move,” says Reicherter. Keep doing your daily activities. Make the beds, go to work, walk the dog. Once you’re feeling better, regular aerobic exercises like swimming, bicycling, and walking can keep you — and your back — more mobile. Just don’t overdo it. There’s no need to run a marathon when your back is sore.
Stay strong. Once your low back pain has receded, you can help avert future episodes of back pain by working the muscles that support your lower back, including the back extensor muscles. “They help you maintain the proper posture and alignment of your spine,” Reicherter says. Having strong hip, pelvic, and abdominal muscles also gives you more back support. Avoid abdominal crunches, because they can actually put more strain on your back.
