An anaesthetic method that kills pain without producing numbness or preventing movement has been developed. Current local anesthetics work by indiscriminately blocking all the channels in a nerve cell, so they can block movement and sensation as well as pain.

Capsaicin is already in use as a painkiller for conditions where pain fibres are overactive. Applying it over stimulates the nerve endings and de-sensitises them, persuading them to stop overreacting. But, as its link to chilli peppers suggests, it produces an uncomfortable burning sensation and can't be given in high doses. As the capsaicin and anaesthetic are applied at the same time, the capsaicin grants the anaesthetic admission to the cell, where activity is dampened down so that pain (including the burning sensation) is relieved.

Although the medication involves a combination of two compounds to go through the pain, it can still leave other functions of the nerve unaffected thus patients can still move the muscle or body part even while they are under anaesthetic. Those who will benefit from it this medication are those going through childbirth and for dental procedures as well. It can be considered a great medical breakthrough.
