ASSESSMENT and PLAN   This is a 40 y.o. female who presents with nausea vomiting diarrhea, myalgias, diffuse abdominal cramping, severe global headache, onset about 2 hours after first dose Moderna COVID-19 vaccine.  Exam with intact mental status, neurologic system.  Abdomen with some diffuse tenderness but no evidence of peritoneal sign.  She had diffuse palpable soft tissue muscular type tenderness through her upper extremity shoulder and bilateral paraspinal back.  She had no meningeal signs.  She had no cardiorespiratory signs or symptoms.  Her chest was clear.  Voice normal.  Swallowing normal.  Oropharyngeal region normal.   Initial ED ED management focused on rehydration, antiemetics and subsequent treatment for presumptive anaphylaxis with likely system involvement gastrointestinal and neurologic.  She was treated with Solu-Medrol, famotidine and acetaminophen.  She improved during ED course and did not require epinephrine.  Symptoms at ED reevaluation/discharge were resolved.   Clinical impression favors anaphylaxis over medication side effect given time course and abrupt onset of symptomatology and signs.  She has a distant history of anaphylaxis to coconut-based product in her past.  She has no history of ongoing allergic chronic history otherwise.  Other organ systems appeared stable at onset and through ED course including cardiovascular and pulmonary.   Plan is for discharge home with rest fluids.  She will have a course of steroids/prednisone and famotidine.  She was sent home with an EpiPen and understands use and precautions.     Discussed ED "return immediately if" parameters with patient. Ongoing FOLLOW UP evaluation/care coordination via PCP recommended. Patient voices good understanding of current evaluation, follow-up & return recommendations and discharge instructions.
