Introduction
Pain-relieving injections are usually administered via intramuscular, intravenous, or subcutaneous routes. These methods allow the medication to enter the bloodstream more rapidly and quickly distribute throughout the body to the site of pain or to nerve endings involved in pain perception, thereby providing analgesic effects. Commonly used drugs include morphine and celecoxib, which can offer relatively long-lasting pain relief.
Generally, postoperative pain-relieving injections can provide pain relief for about 6 to 8 hours. The detailed explanation is as follows:
Pain-relieving injections are usually administered via intramuscular, intravenous, or subcutaneous routes. These methods allow the medication to enter the bloodstream more quickly and rapidly distribute to the site of pain or the nerve endings associated with pain, thereby achieving analgesic effects. Commonly used medications include morphine and celecoxib. These drugs typically belong to long-acting or sustained-release types, which remain stored and gradually released in the body over an extended period, thus providing relatively prolonged pain relief—usually lasting 6 to 8 hours. If pain-relieving injections are needed, they should be used under the guidance of a qualified physician to avoid improper use that could cause harm to the body.
Maintaining healthy lifestyle habits in daily life is recommended, including avoiding spicy and irritating foods, which may otherwise hinder recovery.
