Heat and cold therapy
Heat therapy can improve blood circulation due to the sudden increase in temperature. Heating pads and warm water bottles may be used to apply the heat. Cold therapy, on the other hand, will reduce the blood flow on the applied area as well as reduce the nerve activity. It also numbs down the affected body part, causing the pain to subside. This can be done by applying ice packs on the affected area or by taking a cold shower. Note that there is a risk involved when applying heat or cold therapy to the body, and prolonged exposure can lead to further damage.
