Himehara Clinic, located in Himehara, Matsuyama City, Ehime Prefecture, is a medical clinic specializing in pain management and internal medicine, with a focus on nerve block therapy. According to the clinic's official website, nerve block therapy is a treatment that uses local anesthetics to block sensory nerves and sympathetic nerves that transmit pain, with the goal of cutting off the vicious cycle of pain and activating natural healing abilities. Persistent pain stimulates the sympathetic nerves, leading to vasoconstriction and poor blood circulation, while muscles become tense and pain-inducing substances increase, so preventing this vicious cycle is important. The clinic hours are from 9 AM to noon, with closed days primarily on Sundays and holidays, though this may change depending on the fiscal year. The clinic offers English language services, has parking available, and is barrier-free accessible.
