Excluding physiological reasons such as heavy physical work or incorrect posture while taking the pill, generally speaking, taking Zhi Bai Di Huang Wan as prescribed by the doctor will not cause back pain.

Low back pain is a common clinical symptom, mainly manifested as pain in one or both sides of the waist, belonging to the category of “lumbago” in traditional Chinese medicine. Lumbar pain is divided into real and imaginary, the real one is mostly due to feeling dampness or bruises and injuries caused by blood stasis blocking the meridians, and pain caused by poor qi and blood flow; the imaginary one is mostly due to congenital insufficiency, overwork, prolonged illness and frailty, and pain caused by insufficient qi and blood not being able to nourish the meridians in the old age. If cold-dampness lumbago can be seen in the lumbar cold pain, the treatment is to dispel cold and dampness, warm through the meridians; damp-heat lumbago can be seen in the lumbar pain with burning sensation, the treatment is to clear the heat and dampness (to remove the body of heat and dampness), soothing the tendons and relieving pain; Blood stasis lumbago can be seen as stabbing pain in the waist with pain in a fixed place, the treatment is to activate blood circulation and eliminate blood stasis (to promote blood circulation and eliminate blood stasis in the body), and to regulate qi to relieve pain (to relieve pain by unblocking qi); kidney deficiency lumbago can be seen as soreness and pain in the waist and likes to be pressed and kneaded, the treatment is to tonify the kidneys and benefit the essence (to replenish the kidney essence in the body). Please follow the doctor’s instructions when taking the medication and seek medical advice as soon as possible if symptoms of back pain occur.
