Therapeutic measures were taken as a result of myocardial infarction, fatigue, chills, decreased appetite, myalgia, pyrexia, feeling of body temperature change, movement disorder, constipation, constipation, gastrointestinal disorder, illness, fibrin d dimer increased, hepatic enzyme increased, anaemia, hiatus hernia. No covid prior vaccination. Clinical course: The day of everything seemed normal was a little tired. The day after had chills, no appetite, muscles hurt, fever, hot/cold, couldn't move a lot. Called into work. Was constipated. Patient's digestive tract felt like it shut down. Went to work the next day, but was still really sick. Same symptoms, constipation worse. The third day (Sunday) woke feeling like she was having a heart attack. Went to the emergency room, was tested for a heart attack. Pains subsided, but D dimer was high, Liver levels were a little high, was anemic. Was admitted to the hospital for a day. The doctors found very little wrong other than maybe a hiatal hernia attack. Even did a stress test which was normal. Put patient on Lipitor, but even her cholesterol levels were 177. After two weeks, things seem to be getting better. The doctors don't believe her, though, that this could be shot-related.  Follow-up attempts are completed. No further information is expected.
