It's not underarm, it's between the armpit and the breast and it is a baseball or tennis ball size. It's the same arm she got the shot in. She states that the paper they gave her where she got to shot says that sometimes the lymph nodes get swollen. She doesn't know if this was part of the shot. She called her doctor, and unfortunately, he was not in today. She states that she was in bed all day and only went out to walk to dog. She didn't feel good the next day. Sunday, she was feeling a little better. She wasn't going to call but then when she got this, she was like no, no something isn't right. She was on the bowl this morning, and felt weird, she felt under her arm and it felt weird, and she looked in the mirror and she was like holy, because it was big. She called the doctor; he was not there but they took the information.  No follow-up attempts are possible. No further information is expected.
