The patient inquired if the injection wasn't put in correctly and it was put in the tissue and not the muscle. The reporter mentioned that his wife said the needle didn't go in as much as when she got her injection, so he was wondering if it was administered in the right way and also asking if part of the needle could have broken off and if that is what is causing the redness and swelling to his arm. His doctor assured him the needle could not break and stated that his said that it did not look like the injection was as deep as hers since she was watching him get his vaccine. The reporter also inquired if that could have caused an issue if it was not administered deep enough. He mentioned that he waited several hours before checking infection site [pending clarification] and noticing the swelling and redness.
