Conventional pain-relieving injections: These typically use morphine or anti-inflammatory analgesics, administered via intramuscular injection or intravenous drip into the systemic circulation. Their effects last only a few hours and lack specificity.
ESI injections: These inject the medication directly into the nerve compression site, providing more precise pain relief, which can often last for weeks to months.
👉 Note: ESI can control pain, but it cannot cure the underlying cause.
