Patient had the vaccine first dose on Monday (26Jul2021)and it was not very comfortable. This was pretty painful, she flinched. She could not imagine why and then she stayed in the store and she started getting nauseous. She got a cup of water. Her arm was getting stiff so she went to the grocery (store) and she was trying to keep her arm mobile. She did not want it to lock up on her. She finally took the cotton off and there was a lot of blood on the cotton. Then when she came home she said her arm was sore. There was a lump there so she looked in the mirror and she had a bruise and a knot in her arm. Her cousin (who was a nurse) said she should report that. She went to bed yesterday at 5:30/ 6pm and it was 9:45pm when she woke up she thought it was 3 am in the morning. She was knocked out and she wanted to get up. She was not sure if the vaccine was done properly. It was really sore. She did not feel the same when she had her flu shot last time. Done in right arm.
