The patient previously took novocaine but was allergic.  She got all this information when she got the vaccine on Monday at (place name) in (state name). It tells all the side effects from the first injection. She wanted to report that it is the same arm that she got the vaccine in. She has swelling and joint pain in the little finger on left arm.  It says you can have joint pain, but nothing about swelling. She thought she better report it. This was her first shot. She is supposed to get the second one on 18Jan2021. She wanted to make sure she can take it. She received the vaccine on 28Dec2020. She laid around that day. Today is the first day she doesn't have arm pain and swelling at the injection site.  It was the first time she has had arm pain. She has never had that with flu shot. The arm pain started within the 15 minutes she was observed. It hurt like hell until that day. She got a bruise at the injection site. It bled a little bit when she put it in. Swelling and joint pain in the little finger on left arm: she doesn't know if it was later that day. She can't remember. She really noticed it yesterday. She has never had joint pain or swelling. She doesn't have any problems with arthritis. Now her little finger is bigger than the rest of her fingers. It hurts because of the swelling. She doesn't want to take anything. It might be fluid. She has a high pain tolerance. She keeps bending it thinking it will get better. It isn't as bad, but its still swelled up. At first she thought it was better, but it is still pretty swollen. To her this is a reaction. She was thinking if she took paracetamol before, it wouldn't hurt as bad, but she can't remember if she took it that morning. She takes 500mg before bed for the heck of it at night. It helps her sleep better. She has allergies and can have an asthmatic attack from cat dander and perfume. They think she was allergic to the preservative in the flu shot, but she has never had any trouble with the flu shot since. She has environmental allergies. They thought she was allergic to Novocaine once at the dentist office. Who knows, it only happened once. She's been to the dentist many times and who knows what they injected and why she reacted that way. She felt like she was going to pass out. They don't give it to her anymore. She doesn't know what was in it. She is worried since this vaccine is emergency authorization. She doesn't want to get the next one and have a worse reaction. She is not sure if she should be worried. The events of swelling and joint pain in the little finger on left arm were assessed as medically significant.
