Ninaga Anesthesia Clinic is a medical clinic located in Kosaka, Higashiosaka City, Osaka Prefecture, specializing in pain management and internal medicine. The clinic provides services in English and operates an outpatient department specializing in the diagnosis and treatment of pain, which accounts for approximately 80% of medical conditions. The clinic primarily uses a combination of nerve block therapy and pharmacotherapy. Nerve block therapy involves using small amounts of local anesthetic to temporarily block nerve function. By improving blood flow and effectively delivering oxygen and nutrients, this therapy promotes the recovery of nerve damage and is expected to enhance the body's natural healing ability. Since local anesthetics are rapidly metabolized in the body, the procedure can be repeated without restrictions and is covered by health insurance. Conditions treated include headache, facial pain, trigeminal neuralgia, traumatic cervical syndrome, postoperative scar pain syndrome, cervicobrachial syndrome, shoulder stiffness, cervical disc herniation, cervical spondylosis, frozen shoulder, low back pain, acute lumbar sprain, lumbar disc herniation, sciatica, lumbodorsal pain, intercostal neuralgia, spinal canal stenosis, finger circulatory disorders, pain from herpes zoster, and postherpetic neuralgia, among others.
