For lumbar disc herniation, heat therapy can be used as a treatment, mainly during the symptom relief phase. By applying heat, the temperature of the lumbar muscles and skin can be increased, relaxing the blood vessels within the muscles and accelerating blood flow, which can reduce irritation to the dura mater and nerve roots, easing clinical symptoms. Heat therapy can be applied using a hot towel, traditional Chinese medicine herbal fumigation, or devices like an infrared spectrum heater, microwave therapy, or infrared therapy device. In addition, other treatments should be combined, such as lying flat on a hard bed, applying traction to the lumbar area, using acupuncture and moxibustion, and strengthening lumbar exercises to help alleviate symptoms. Patients should avoid vigorous activities and keep the lower back warm.
