Patient didn't want people in her family to say that the vaccine had hurt their sister, and discourage them from getting it. Patient said, after getting the booster her arm won't go back at all, she is sleeping with it on top of a pillow. Patient thought it would go away but it didn't, and she didn't want to tell nobody about it if it could discourage people from getting the vaccination. Patient said it kept getting worser, so she told the doctor and then the doctor got her taking something for inflammation. She says her arm was swollen, with fluids in her arm after the last vaccination. Patient said they did the x-ray and found fluid in there, then did the MRI and did all that. It was her right arm that she can't straighten out, and said she is right handed and got all three vaccinations in the right arm.
