To treat low back pain spasms at home, apply a hot or cold pack to the affected area, recommends WebMD. Low back pain can also be alleviated by resting, taking over-the-counter pain relief medications or exercising.
Experts recommend resting for 48 hours after noticing low back pain or being injured, states WebMD. Once the spasms and pain subside, it is important to become active as soon as possible. Staying in bed for too long can cause low back pain to become worse.
A patient should apply a heating pad or disposable heat wrap directly to the problematic area, notes WebMD. This relieves pain and discomfort while also keeping swelling and inflammation down. Heat helps to stop spasms by increasing the oxygen supply to the area and dilating the blood vessels. A cold pack reduces pain by decreasing the flow of blood to the affected area and shrinking the blood vessels.
Over-the-counter pain relievers such as acetaminophen, naproxen or ibuprofen may keep low back pain at bay, according to WebMD. Gels or topical creams with numbing agents may help to reduce pain. Doctors may recommend that patients stay mobile by performing certain exercises and physical therapy maneuvers. A patient should speak to his doctor or physical therapist before attempting to exercise with back pain.
