Numbness in wounds is often caused by nerve loss, because whether the wound is caused by trauma or surgery, there will be localized discrete damage to the skin nerves, and then there will be a noticeable numbness, which can usually be reduced gradually with time. However, most patients need more than 2-3 months, sometimes for several years. If the patient’s condition is more serious, vitamin injections can be given to help recovery, but the effect is generally mainly dependent on the usual dietary adjustments to help recovery, for example, appropriate intake of vitamin-rich fruits, commonly found in kiwis, apples, duck pears, etc., and appropriate intake of low-fat high-quality proteins, such as fresh fish and shrimp, leaner beef, etc.. Some patients can also go to the hospital for physical therapy to help relieve the discomfort.
