I have painful nodules on the gluteus because of the application of intramuscular injection. How do I get rid of them, can I continue to apply the medication because I've heard that the nodules do not let the drug be absorbed? I'm waiting. Thankful.
Expert answer:

You can continue to apply the medication as prescribed by your doctor, make warm compresses on the nodules that can help you to break down the nodules faster.
