What happened when one leg started to go numb after surgery for a herniated disc?

The common causes of numbness in one leg after lumbar herniated disc surgery include normal phenomenon, compression of nerve root, nerve injury, and so on.
1. Normal phenomenon: If both pain and numbness existed before the surgery, the pain symptoms can be relieved faster after herniated lumbar disc surgery, so the numbness symptoms will be obviously felt, and the numbness symptoms can be gradually reduced after resting under normal circumstances.
2. Compression of nerve root: nerve edema or hematoma at the operation site may occur after the operation, resulting in compression of the nerve root and numbness in the leg.
3. Nerve damage: If the nerve is damaged during the surgery, numbness of the leg may also occur, but the lumbar herniated disc surgery is a very mature surgery, and the probability of this happening is very low.
If you start to feel numbness in one leg after lumbar herniated disc surgery, you should go to the hospital in time to find out the cause and carry out targeted treatment.
