Symptom narrative

Immediately upon standing, she experienced presyncope, visual disturbances described as "seeing stars," and dyspnea. She self-administered Benadryl 25 mg due to severe rigors. Despite this, rigors persisted, and she was advised by the rapid response nurse and on-call physician to take an additional 25 mg of Benadryl, totaling 50 mg. Her symptoms improved, but she was transported to the ED for further evaluation. She was monitored in the ED without further treatment needed. She has had persistent brain fog, headache, and nausea even though it's been more than a week. This plus the idiopathic urticaria which started a few weeks before vaccination suggest possible mast cell activation syndrome.
