How many days it takes for a lumbar misalignment to heal depends on different conditions and cannot be generalized. If the misalignment is only a mild sprain, it usually gets significantly better in 3-5 days after resetting. If the misalignment is very pronounced and the pain is very severe, it may take 7-10 days at this time. If the subluxation is accompanied by isthmus fracture, lumbar spine slippage and nerve compression, the pain may not be relieved by rest alone, and treatment is generally required, which usually takes 2 weeks and may take up to a month. If the lumbar subluxation is accompanied by pathological signs, simple conservative treatment may not be effective at this time.
