Edema can disappear in about 1 week after lumbar foramenoscopy surgery, but the exact time of disappearance of edema can’t be determined due to the different recovery time of patients with different physical condition and different duration of surgery. Edema after lumbar laminectomy is generally normal, and can be promoted through hot compresses and other ways to accelerate blood circulation, accelerate the absorption of edema, and reduce the patient’s symptoms. If the symptoms are serious, you can use furosemide, spironolactone and other diuretics as prescribed by the doctor. Usually, the edema caused by the surgery will disappear gradually in about a week. After lumbar foramenoscopy surgery, patients should pay attention to bed rest, strengthen nutrition, eat more protein-rich food, reduce the weight of the waist, accelerate wound healing and recovery. If the edema after lumbar foramenoscopy surgery does not go away, you should go to the hospital for regular treatment.
