There are several ways to relieve back pain after cesarean section: 1, keep warm: you can keep your lumbar abdomen, lumbosacral region, buttocks and lower limbs as warm as possible to avoid the onset of back pain aggravated by cold and chills, etc. 2, massage: you can massage your lumbar abdomen, massage your enlarged uterus, and massage the spasmodic lumbosacral muscles, which effectively improves lumbosacral muscle spasms and promotes uterine contraction effectively through massage, thereby relieving back pain caused by lumbar muscle tension, lumbosacral muscle spasm and poor uterine contraction. The massage can effectively improve the spasm of lumbosacral muscles and effectively promote the contraction of uterus, thus relieving the low back pain caused by the tension of lumbar muscles, spasm of lumbosacral muscles and poor contraction of uterus. If the back pain is serious, go to the hospital for consultation.
