Have surgery only if it is necessary. All surgery can have complications. Actually, complications from neuroma surgery are rare when an experienced surgeon does the procedure. Still the there is a small chance that numbness, infection, prolonged postoperative pain and even a regrowth of the neuroma can occur. If surgery is needed I recommend against general anesthesia.
Today there is an excellent anesthesia technique involving sedation and local anesthesia.
The combo produces a gentler experience and is safer than general anesthesia. The sedation makes you feel like you havent slept in days. You dont really know what is happening for about an hour. With the local anesthesia placed around the surgical site you dont feel the procedure. A neuroma can be a disabling entity.
