Hemorrhoids using infrared light irradiation can control the symptoms of hemorrhoids, which can cause the nucleus to shrink, edema to subside, etc., but it does not make the nucleus disappear completely, as long as it can control the symptoms it can be called a cure for hemorrhoids. When local thrombosis or local infection can lead to enlargement, pain, edema and other symptoms of the hemorrhoid nucleus, physical therapy can be used, such as laser irradiation, infrared irradiation, etc. The above physical therapies have the therapeutic effects of activating blood, removing blood stasis, reducing swelling and relieving pain, so they are better adjunctive treatment for acute symptoms of hemorrhoids and are more commonly used. Post-operative patients with local incision edema can also use infrared light irradiation, which can promote the local incision edema to subside and also promote incision healing.
