The procedure you received was an injection suitable for people with anemia. I don't remember the doctor's name. The pain and recovery period were almost painless, but it stung, and I scratched it, and it turned red. Other than that, everything else was fine. However, the recovery period wasn't just a little, it was a long one. It was about two to four days. The doctor told me that it hurt a lot because I was anemic and was born smaller than other people. That's probably why the recovery period was so long, and my hand hurts. My experience with the treatment was that the hospital was very clean and the doctors were kind, so I wasn't scared or nervous when I came.
