The evening following vaccination, the patient developed symptoms of fever to 102-103, throat tightness, facial swelling, and body aches. The mother gave him a dose of Benadryl and he had improvement in swelling. The mother reports they had a home pulse oximeter and felt like his oxygen level was in the high 80s. However he did not go to the urgent care or ER for evaluation. The family is concerned about a possible allergic reaction. Our triage nurse recorded the following…”Called mom. and she states they had a really bad weekend, flu/Men B. She thinks he had an allergic RXN- had every sx on the handout. High fever , could barley lift his arm- extremely painful- difficulty with PJ’s. Saturday slept all day 102.7 fever. Felt tightening in throat and Saturday night had face swelling, fever came down with compresses and alternating Tylenol and Ibuprofen. No antihistamine. Very nauseated. Today no fever, still throat tightness and slightly puffy face. Kept him home today. No diarrhea. Arm is better today. Pulse OX on Saturday read 73-83, felt SOB – book said he was still in the normal range. Pulse OX yesterday was 93% and 97% today. Told mom I think he needs to be seen- placed on hold and relayed the above and he states he should be seen in UC. Recommended that he be seen in UC given the ongoing throat tightness and puffy face- may need steroid/antihistamines- mom asked if she could just give him Benadryl- needs documentation of symptoms- should be seen- mom plans to take to clinic. Patient states that throat feels tighter then yesterday but is not SOB- can hear him talking and mom said he is breathing thru his nose. She is asking for letter for school- in case she forgets to ask at UC. “
