She was asked to wait for 15 minutes, 5-10 minutes of waiting, she felt like something was in throat, so she kept clearing it. Patient felt tingling on both hands and fingers. Her voice started to change. She informed the ER team there, the ER nurse described her face turning red to white to purple. ER nurse started an IV right on patient's right AC, gave her a shot of Benadryl, steroids and the epi pen right through pants. Patient felt everything in mouth as tongue felt like it was growing, but she can breath. Patient was route to the ED via wheelchair, everything started to look hazy, she was having chest pain radiating to left scalpel, and jaw. Patient couldn't think of the words to say as it was hard to breath. When got to the ED they gave her another dose of Benadryl, solumedrol, decadeon, HHN tx with epi and that worked. Patient felt her throat opening up and started talking but then came the chills. It took almost 3 hours to clear the symptoms, even though her heart rate is racing (prob due to the meds), she opted to go home. The outcome of "heart racing" was not recovered, of other events were recovered on 18Dec2020.  No follow-up attempts are possible. No further information is expected.; Sender's Comments: A possible causal association between administration of BNT162B2 and the onset of anaphylactic reactions with tongue swelling/voice alteration/hard breath/tingling/something in throat/skin discoloration, chill and chest pain cannot be excluded, considering the plausible temporal relationship and the known adverse event profile of the suspect product.
