If a patient experiences leg pain after a puncture treatment, it may be due to the presence of nerve edema, nerve compression, or puncture damage to the nerve, among other causes. When treating this kind of patients, we need to take measures such as braking and resting, physical therapy, application of relevant drugs and surgical treatment. 1. Braking and resting: after the symptoms appear, do not force to move the lower limbs. At this time, the patient can take the side lying position or prone position, keep bed rest. 2. Physiotherapy: for some patients with mild lesions, you can apply relevant physiotherapy on the basis of bed rest, such as common infrared therapeutic irradiation, hot compresses and so on. 3. Application of relevant drugs: for some patients with obvious pain symptoms, you can give them some drugs with anti-inflammatory, decongestive and nutritive effects on peripheral nerves. For example, nimesulide, methylcobalamin and so on are commonly used. 4. Surgery: For some patients with particularly serious lesions, such as patients with related nerve function loss, surgery can be taken. For example, for the suspected lesion area, the corresponding nerve can be explored and repaired through surgery. It is recommended that patients should not panic after the occurrence of the above situation, but should return to the hospital as soon as possible for follow-up.
