Which department should I see?


Hello doctor, I underwent a bunion surgery on my fifth toe in January and July, both under spinal anesthesia.
Several months have passed, and I often feel lower back soreness and pain.
Could this be a side effect of the spinal anesthesia? Thank you, doctor.

Hello, based on your description, the likelihood of the issue being caused by anesthesia is low.
It is more likely related to spinal or muscular problems.
I recommend that you schedule an appointment with an orthopedic specialist.
Thank you for your inquiry.

After undergoing spinal anesthesia for your toe surgery, it's understandable to be concerned about the back pain you're experiencing. While spinal anesthesia is generally considered safe, it can sometimes lead to complications or side effects, including back pain. However, it's important to note that the back pain you are experiencing may not be directly attributable to the spinal anesthesia itself.

Spinal anesthesia involves the injection of anesthetic agents into the epidural or subarachnoid space of the spine, which temporarily blocks sensation and motor function in the lower body. While the procedure is typically performed with a fine needle, some patients may experience soreness or discomfort at the injection site, which can lead to localized back pain. This discomfort usually resolves within a few days to weeks after the procedure.

In your case, since you mentioned that the back pain has persisted for several months, it may be indicative of other underlying issues unrelated to the spinal anesthesia. For instance, prolonged immobility during recovery, changes in posture, or compensatory movements due to pain in your toes could contribute to back discomfort. Additionally, if you had any pre-existing conditions, such as lumbar disc issues or muscle imbalances, these could be exacerbated by the surgery and subsequent recovery process.

To address your concerns, here are some steps you can take:
1. Consult Your Surgeon or a Specialist: It's crucial to discuss your symptoms with your surgeon or a healthcare provider who specializes in pain management or orthopedics. They can evaluate your condition and determine if further imaging, such as an MRI or X-ray, is necessary to rule out any structural issues.

2. Physical Therapy: Engaging in physical therapy can be beneficial. A physical therapist can design a rehabilitation program tailored to your needs, focusing on strengthening the muscles around your spine, improving flexibility, and correcting any postural issues that may be contributing to your pain.

3. Pain Management: If the pain is significant, your doctor may recommend pain management strategies, which could include medications, injections, or alternative therapies such as acupuncture or chiropractic care.

4. Activity Modification: Pay attention to your daily activities and posture. Avoid prolonged sitting or standing in one position, and incorporate regular movement and stretching into your routine to alleviate tension in your back.

5. Monitor Symptoms: Keep track of your symptoms, including any changes in intensity or location of the pain. This information can be valuable for your healthcare provider in determining the best course of action.

In conclusion, while spinal anesthesia can lead to temporary discomfort, persistent back pain several months post-surgery may be due to a variety of factors. It's essential to seek professional evaluation to identify the underlying cause and develop an appropriate treatment plan. Remember, early intervention can often lead to better outcomes and a quicker return to normal activities.
