Anesthesia: Is Numbness Normal After Surgery?

Anesthesia!

Doctor, I would like to ask you about something.
I had hernia surgery on the afternoon of December 1st (with lower body anesthesia), and it has been almost 20 days since my discharge.
I still have no sensation in the groin area below the incision.
Is this normal? If it is normal, why is this happening?

Hello, lower body anesthesia can sometimes lead to a temporary neurological syndrome, usually affecting the lower limbs, which typically improves within one week to one month.
You can directly consult the surgeon regarding your condition, and I believe the surgeon will provide you with a response.

More Info

After undergoing surgery, particularly one involving regional anesthesia like your hernia repair, experiencing numbness in the area around the incision site can be a common occurrence. However, the duration and extent of numbness can vary significantly from person to person, and understanding the underlying reasons can help alleviate concerns.

Firstly, it's important to recognize that anesthesia, especially regional anesthesia, works by blocking nerve signals in a specific area of the body. This is achieved by administering anesthetic agents that temporarily inhibit the function of the nerves responsible for sensation in that region. In your case, the numbness in the groin area may be a result of the anesthetic affecting the nerves that supply sensation to that part of your body.
Typically, the effects of regional anesthesia can last for several hours to a couple of days post-surgery, depending on the type of anesthetic used and individual patient factors. However, in some cases, patients may experience prolonged numbness or altered sensation in the area, which can last for weeks or even months. This phenomenon is often due to nerve irritation or minor nerve damage that can occur during the surgical procedure, especially if the surgery involved manipulation of tissues near the nerves.

In your situation, having numbness for nearly 20 days post-surgery is on the longer side, but it is not necessarily abnormal. It is crucial to monitor the numbness and any other symptoms you may experience. If the numbness is accompanied by other concerning symptoms, such as increasing pain, swelling, or changes in color of the skin, it would be advisable to consult your surgeon or a healthcare professional for further evaluation.

The healing process after surgery can be complex, and nerves can take time to recover. In many cases, as the surgical site heals and inflammation decreases, sensation may gradually return. However, some patients may experience residual numbness or altered sensation long-term, which can be a result of the surgical procedure itself or the anesthesia used.

If you are concerned about the numbness persisting, it would be beneficial to discuss this with your healthcare provider. They may recommend a physical examination and possibly imaging studies to rule out any complications such as nerve entrapment or other issues that could be contributing to your symptoms.
In summary, while numbness after surgery can be a normal part of the recovery process, especially following regional anesthesia, the duration and severity of symptoms can vary. It is essential to stay in communication with your healthcare provider to ensure that your recovery is progressing as expected and to address any concerns you may have.

Dr. Zheng Zhong reply Neurosurgery
Lumbar spine surgery should not be related to hand numbness. There is still a 10% chance of recurrence (reherniation) after lumbar microdiscectomy. It is recommended to return to the outpatient clinic to consult with the surgeon for further evaluation.
