Medical acupuncture aids healing and pain relief in three primary ways. Firstly, it stimulates blood flow to the area, delivering fresh nutrients essential for muscle healing. Secondly, it reorganises pain signals to the spinal cord, reducing dull aches in the targeted muscle and others connected by the same nerve route. Thirdly, it stimulates nerves that prompt the release of hormones like serotonin and noradrenaline, which help relax and calm the body.
