Get moving, get stronger, and stretch: Exercise is a great way to improve back strength and relieve chronic back pain.
Try medications: Depending on what your doctor may recommend, drugs like aspirin can relieve back pain. But overuse of these meds can cause side effects.
Make time for massages: Massage therapy can also help soothe the sore area, especially chronic back pain.
Try hot pack / cold pack: When back pain strikes, try a hot or cold pack for temporary relief. Heat therapy promotes blood flow to the inflamed part of the body, which allows the muscles to relax. Cold therapy slows blood flow to the inflamed body part, which reduces swelling.
Regardless of which pain relief method you try, time and symthom matters. Go see your doctor if your back pain worsens or lasts for more than three weeks.
