Is it normal to have a lump under the skin when injecting growth hormone?

Patient's question:

When the child is anesthetized and receiving growth hormone, a bump forms under the skin after the injection. How can this be resolved? What kind of help is desired: When the child is anesthetized and receiving growth hormone, a bump forms under the skin after the injection. How can this be resolved?

Doctor's answer:

1. When administering anesthetic growth hormone, if the needle angle is too small, causing the anesthetic to swell under the skin, this situation does not need to be resolved; let the skin naturally metabolize the medication. This will absolutely not interfere with the efficacy of the growth hormone, nor will it cause any harm to the child's body.
2. When using a syringe to anesthetize for growth hormone, the correct needle angle is 45 degrees to anesthetize the subcutaneous tissue.
3. Even if the needle enters the subcutaneous tissue, if the anesthetic is administered too quickly, it may still cause swelling. Therefore, the anesthetic speed should be slowed down each time.
