Many causes can lead to symptoms of lumbar pain after lifting heavy objects, such as incorrect labor posture and sprain during bending, resulting in lumbar muscle sprain. This includes acute lumbosacral sprain and acute intervertebral joint sprain, both of which can cause lumbar aches and pains. It is also possible that the patient has a primary disease such as lumbar strain and lumbar disc herniation, plus lifting heavy objects exceeds the load of the lumbar muscles, resulting in soreness of the lumbar muscles. You can apply topical ointments to relieve blood stasis, swelling and pain, such as musk tiger bone ointment and dog skin ointment. It is necessary to rest in bed with brakes and take oral Chinese medicine to invigorate blood stasis and relieve swelling and pain, such as Bone Injury Recovery Pill. Acupuncture treatment or physical therapy such as magnetic therapy, transdermal therapy, electromagnetic therapy, wax therapy, and ultrashort wave therapy can also be used to relieve muscle spasm and improve local blood circulation. If the above treatment does not make the symptoms better, go to the hospital in time.
