Platelet-Rich Plasma Treatment for Peripheral Neuropathy
Peripheral neuropathy is a painful condition where the nerves furthest away from your spine become damaged or diseased. The most common location for peripheral neuropathy to begin is in the feet. It can start off as a tingling sensation and, over time, increases to a burning pain as damage to the nerve increases. Eventually, it can lead to a numb sensation in the toes, ball of the foot and then the whole foot. If this occurs, it can cause balance issues, foot ulcers, and damage to the skin between the toes as you can no longer feel pain or sensation in the foot.
Peripheral neuropathy can be caused by several conditions, such as diabetes or carpel tunnel syndrome. To begin with, it is important to address the root cause of the neuropathy; if at all possible. This is done ideally before addressing the nerve damage directly. This means, for example, we address (and ideally eliminate) carpel tunnel syndrome first, before treating the nerves in the wrist and the hands first.
About the Treatment
Platelet-rich plasma is a safe and effective treatment for peripheral neuropathy. Platelet-rich plasma involves drawing an amount of blood from the patient, spinning it in a special centrifuge (we use Arthex Angel System) which extracts the platelet-rich plasma (PRP). This PRP is then injected to the affected nerves in the foot or wrist. The procedure is conducted in the office and should be repeated up to three times. Research shows a decrease in pain and increase in sensation within three months. However, with my patients, I have seen improvements in 4 weeks with an increase in sensation and decrease in pain.

A 2019 study was conducted on 60 individuals with type II diabetes with concurrent diabetic neuropathy. Half the group received PRP treatment while the other half did not. The group receiving PRP showed significant improvement in pain and numbness at 1 month, 3 months, and 6 months follow up visits.
Another study specifically focused on carpal tunnel syndrome found that 1 injection of PRP to the wrist significantly decreased pain and numbness at 1, 3 and 6 months.
