Is hypodermic injection bulge normal?

It is normal to have a bulge after a hypodermic needle injection. This is mainly because after subcutaneous injection, the injection needs to be absorbed through the skin to achieve the purpose of treatment. When subcutaneous intramuscular injection is performed, due to the poor absorption capacity of the skin and muscle, it will cause the local drug to accumulate and produce a bulge. In this case, we can promote local blood circulation through local hot compresses and other methods, accelerate the absorption of drugs by muscles and skin, and relieve local symptoms. If local edema or pain occurs after hypodermic injection, we can also use hot compress to improve the symptoms.
