Why does my buttock hurt for a long time after receiving a fever-reducing injection, and what should I do?

Generally speaking, "butt" refers to the buttocks. Persistent pain in the buttocks after receiving an intramuscular injection for fever may be caused by drug irritation, nerve damage, muscle injury, hematoma, infection, or other reasons. Symptomatic treatment is recommended. Specific analyses are as follows:

1. Drug Irritation

The injected medication may be highly irritating. Once delivered into the muscle, it can irritate the muscle tissue, causing symptoms such as pain and swelling in the buttocks. Usually, no special treatment is required; symptoms gradually subside once the medication is fully absorbed.

2. Nerve Damage

When administering an intramuscular injection in the buttock, incorrect placement may irritate or damage the nerves in the area, leading to persistent pain. Under a doctor's guidance, neurotrophic medications may be prescribed, such as mecobalamin tablets, oryzanol tablets, and vitamin B1 tablets.

3. Muscle Injury

Improper technique during intramuscular injection may injure the buttock muscles, resulting in localized pain, redness, swelling, or bleeding. It is recommended to apply heat therapy or massage to the affected area under medical guidance to promote local blood circulation, relax muscles, and alleviate symptoms.

4. Hematoma

If small blood vessels in the buttock skin are damaged during injection, capillary rupture may occur, leading to subcutaneous hematoma. This can cause localized pain, bruising (bluish discoloration), and swelling. Adequate rest is advised, along with avoiding strenuous activity. When necessary, warm compresses using a heated towel may be applied under medical supervision to improve symptoms.

5. Infection

If proper disinfection is not performed during injection, bacteria or viruses may enter the body through the injection site, causing infection. Symptoms include redness, swelling, and pain around the injection site, possibly accompanied by fever. Antibiotic treatment under a doctor’s guidance is recommended. Commonly used antibiotics include cefalexin capsules, cefradine capsules, and cefixime capsules, which help inhibit or kill bacteria and relieve symptoms.

It is advisable to seek timely medical attention for thorough evaluation and accurate diagnosis. Follow your doctor’s instructions for active treatment. Any discomfort should be managed with appropriate medication only as directed by a healthcare professional to avoid adverse drug reactions due to self-medication.
