Both doses were given from the same vaccination site. After the second dose, she got really sick. She stayed home from teaching the next day on 19 Mar 2021. It took a couple days before getting back to normal. After a few months on 20 Apr 2021, she had a shoulder surgery. Within a few weeks by mid-May 2021, her elbow joints hurt. She was not sure if it was associated with the recovery or not. She had physical therapy after the surgery, but she still had pain in her joints, more specifically in her hands and feet. She also had pain in her knees and hips. It was not normal because she had been athletic all her life and still was until this point. In the beginning of Jun 2021, she went for grocery shopping when suddenly every joint in her toes hurt. She was really worried, so she went to her doctor on 09 Aug 2021. The doctor told her it could be rheumatoid arthritis, but her test results did not show that at all. They still did not know what it is. She had ulcers, so she cannot take certain medications. She was prescribed Celebrex and drinks more water, ups her vitamin D, takes fish oil. She was not liking where she's at right now. She wakes up in the morning and it takes about an hour to get going. Her joints, especially her hands, are so stiff and so painful. She can barely open jars, which was easy for her before. Her feet hurt so bad that it's like every single bone hurts like she's walking on rocks. She stands up really slow and had to stretch for a minute before starting to walk. She just felt achy. Something was with her joints. She wishes that she had waited longer to get vaccinated. Her fingers were so swollen that she could not wear some of her rings. She was down to two shoes that will fit her because those were more supportive. The pain shoots into her toes. The patient was worried that this won't go away or will get worse.
