Why do bum hurt after injecting steriods?

Injecting steroids can cause pain in the injection site due to irritation of the tissue and the potential for inflammation. The substances used may also lead to localized swelling or soreness as the body reacts to the foreign substance. Additionally, improper injection technique or using a needle that is too large can exacerbate discomfort. It's important to follow proper guidelines and consult with a healthcare professional to minimize these effects.
