As long as the peripheral nerve cells have not been killed, they have the ability to regenerate. In some cases the tingling feeling can be reduced with drugs originally developed for treating epilepsy or depression. The NHS also recommends capsaicin cream or a lidocaine plaster if the pain is confined to small and particular area of your body. Capsaicin is the substance that makes chilli peppers hot. It is thought to work by stopping the nerves sending pain messages to the brain. Lidocaine is a local anaesthetic that numbs the area covered by the plaster.
