Rotten! I went to the emergency room in the middle...

Rotten! I went to the emergency room in the middle of the night last week. I was given an injection in the left and right arms by the nurse. As a result, a 6 cm diameter mass appeared on the right arm the next day. It didn t disappear after 3 days. I called and asked. Look at it in a few days, it will disappear normally.
It is the 10th day today, and the lumps have not disappeared. Call me again and ask me to go to the dermatologist.
This is not my own problem. Why should I see another doctor?

It feels like I am only responsible for injections in my department, and the reactions after injections have nothing to do with me! That is the dermatologist in charge, you go to the dermatologist!

I have lived for decades and have never been injected like this before. Is the nurse's injection technique to be reviewed? The follow-up treatment is very negative! Expensive and not recommended hospital!
