Sciatica is divided into primary and secondary types. Primary sciatica is caused by inflammation of the sciatic nerve itself, thus one should visit the Department of Neurology. Secondary sciatica is more common and usually stems from spinal conditions, so initially one should visit the Department of Spinal Surgery. Alternatively, one can visit the Department of Orthopedics, which deals with broader orthopedic issues. If experiencing severe acute pain, a visit to the Pain Management Department can provide rapid and effective pain relief. For frequent episodes of sciatica and interest in rehabilitation, the Rehabilitation Department can be considered. Additionally, traditional Chinese medicine has unique approaches to treating sciatica, so visiting the Department of Traditional Chinese Medicine to try treatments with Chinese herbs and methods is also an option.
