Burning lower back pain typically indicates a chronic condition, not an acute injury, and often involves damage to the nerves. The cause may be sciatica, a herniated disc or other problems that compress the nerves in the back and bring on the burning sensation. Whatever the cause, treating burning lower back pain often involves a doctor's care along with home remedies, especially if the pain does not resolve within a couple of weeks.
Lie down on the floor on your back with a pillow underneath your knees. This position keeps the weight off of your back and allows it to heal. Remain in this position as often as possible for one to two days with five minute breaks every hour to get up and walk around.
Place a heating pad on the sore area of the back for 20 to 30 minutes a few times a day on the third day and subsequent days, as recommended by FamilyDoctor.org, an information website published by the American Academy of Family Physicians. Continue using the heating pad every day until the pain subsides.
Use an over-the-counter pain relief remedy to ease pain. Acetaminophen and ibuprofen are both good options.
Sleep on your side with knees bent and a pillow between your legs, suggests the National Institute of Neurological Disorders and Stroke. You can also use a pillow under your head to support your neck while sleeping.
Exercise your back by lying supine and gently pulling your knee up to your chest. Do 10 of these stretches on each side.
Try using acupuncture or biofeedback to ease the pain if symptoms remain after a few days of rest. Consult a practitioner who is trained in these methods to determine an appropriate course of treatment using these techniques.
Take an antidepressant medication prescribed by your doctor. Antidepressants may be used off-label to relieve lower back pain.
Apply capsicum as a topical plaster to the lower back or take willow bark orally. These herbal remedies for lower back pain have not been studied enough to determine their efficiency but some people may want to try them to see if they offer relief. Discuss herbal remedies with your health care provider to determine appropriate dosing.
Consult with your doctor about whether or not you need surgery or other medical procedures to address the underlying cause that is bringing on the symptom of burning back pain.
