Deep tissue massage (DTM) targets deeper muscle and connective tissue layers to alleviate pain, improve range of motion, and promote healing. It has various sub-types, including myofascial release and trigger point therapy, which aim to break down scar tissue and relax muscles. DTM facilitates healing by improving blood circulation, reducing muscle spasm, and enhancing flexibility. While it offers numerous benefits, potential side effects may include temporary pain or bruising after sessions. It's essential to consider contraindications, such as lack of proper training, before undergoing DTM.
