Patient reported that, after her first dose, she had soreness and stiffness to her right arm. She got her 2nd dose on 17 Feb 2021 and it was done on the same right arm. Ever since she got her first dose, she had soreness and stiffness on her right arm. arm is sore and arm is stiff, were in the muscle of her arm, it travelled up the inner part of the arm next to her under arm. it was in the muscle then comes to the left and come into the top of her shoulder right on the bone in her shoulder blade. it was to the left of where they actually gave her the shot. if she holds her arm straight out, she could feel the pain running up into her shoulder. Reporter was asking if this is normal. She talked to her PCP and he didn't seem concerned. she never had any swelling or rash. Just soreness and pain. she had flu shots last year and reacted the same way, but it went away. But she started having this reaction right away after the 1st COVID shot. Patient had the Pfizer vaccine her second dose 27Feb2021 and she has been to her personal care physician, this was not an emergency, she was having one and it will not go away. From the time she got the first vaccine, her arm got stiff and sore. Patient told them when she went back to second shot that, she wanted it in the same arm, it was her right arm, which is her dominant arm. Reporter stated that, Stiffness and soreness, it will be 4 months this month and it was still there. she stated even when she lays down, she can feel that pressure when she lays on her right side. She's been to her personal care doctor, there's no rash, no swelling, just the stiffness and soreness just persist. she wanted to know if this is anything that she should be concerned about, her. patient stated like put heat on it, she didn't like taking a lot of pills, she was not taking anything. Reporter wanted to know if this is something normal or something she should be worried about. Patient also stated that, she was happy, she doesn't have any regrets, she was blessed that she never got the disease, and she was thankful. Patient said, right after the first shot began, she told them before she had the second shot, she thought that would be a problem but after they didn't see signs of infection, she had the second shot in the same arm. she didn't want the other arm to start having a problem. She was just trying to ignore it, but she just wanted to bring it up now since its been almost 4 months now, she thought maybe she should talk to somebody. She's been to her doctor, he looked at her arm, felt it and basically said it would go away, but it's been 2 months since she saw him, since not swelling, no rash, nothing, just the soreness. Patient stated it started the same day as the first dose. And, she was not like those people, she does not like a lot of drama over being ill, a lot of people do that. she was not in some kind of terrible horrible pain or she would have been to the hospital, it's just there, its nagging, it is always there. its tender sometimes, when she lays on that side and sometimes its sore. she stated its there, it is aggravating. It was persisting, almost like flare ups and sometimes she forgets its even there and doesn't even notice it. It was always early in the morning when she first gets up, maybe it was because she's laying on it because it was her dominant side because it was putting a lot of pressure on it. it was not like every moment of the day it was hurting her it was just a nagging pain sometimes it gets worse and like she said she's not a young woman, she has arthritis in her body, issues with a pinched nerve. She was telling one of friends it may not have anything to do with this shot. At the time of reporting, the outcome of the events were not resolved.
