Umegou Pain and Internal Medicine Clinic, operated by Medical Corporation Kantsukai, is an internal medicine clinic located in Yamazaki, Noda City, Chiba Prefecture. The clinic offers English-speaking services and provides parking and barrier-free facilities. The clinic specializes in the treatment of herpes zoster (shingles) and post-herpetic neuralgia (PHN). For shingles, which develops when varicella-zoster virus becomes active after decades of latent infection, the clinic uses antiviral drugs, anti-inflammatory analgesics, and nerve blocks during the acute phase to reduce pain. For post-herpetic neuralgia, pharmacological treatments including pregabalin, gabapentin, antidepressants, anticonvulsants, and analgesics are administered, with nerve blocks also performed for treatment-resistant cases. Note that nerve blocks for shingles pain affecting the face, neck, and chest require administration by physicians with specialized training due to their strong impact on the respiratory, circulatory, and endocrine systems.
