tenderness between the ear and the base of the jaw; swelling like bean between the ear and the base of the jaw; feverish; Feeling really hot; caller says that there's a node there; arm was sore/a little bit of pain at the injection site; This is a spontaneous report received from a contactable consumer (patient) reported for herself. A 69-year-old female patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Lot number: EN6208, Expiration date: Unknown), via an unspecified route in the right arm on 16Mar2021 at 10:00 (age at vaccination: 69-year-old), as a single dose for covid-19 immunization. Medical history included tachycardia, blood pressure and fibromyalgia for 30 years. Concomitant medications included Verapamil 40mg take one twice daily by mouth (taking 30 years, ongoing) for blood pressure and metoprolol tartrate (METOPROLOL XL) 25mg take one quarter to one half daily and as needed (taking for 15 years) by mouth for tachycardia. Historical vaccine included first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Lot number: EN6198), via an unspecified route in the right arm on 23Feb2021 at 10:00, as a single dose for covid-19 immunization and experienced little bit of pain at the injection site. Patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. Patient had the second dose on 16Mar2021 and the first day everything well except the arm was sore. She had just a little bit of pain at the injection site that lasted a day and half both times. On 17Mar2021, toward the end of the second day after the second dose, she noticed her jaw was tender on the left side/tenderness between the ear and the base of the jaw; noticed a swelling the size of a bean that was tender behind her ear and had a bean like lump that is swollen. She was wondering if that is part of the lymph nodes issue with Pfizer? She would like to know if anyone has reported swollen lymph nodes in this area. She got the shot in the right arm and this is showing up on the left side. Adds she did see a doctor who noted the swelling and mentions it could be related to the lymph node issue with the vaccine. Adds she has also been feeling really hot but each time she takes her temperature it is normal/ she feels hot, she doesn't have fever but feels feverish. She has experienced the feeling feverish without a fever in the past, but this time it seemed more intense. She did email her doctor who said it needs to be seen. She went to see her physician/associate this morning, who said she assumed the bean size swelling behind her ear was part of the vaccine immune reaction and told her to take Tylenol and antihistamine and put warm compresses on it. Patient stated that online there's a doctor who reported swollen lymph nodes in the back of the neck after the covid-19 vaccination (female) and that this is in the Pfizer sheet. The associate also encouraged her to call Pfizer and report. Mentions they were looking for a lump under her arm and not behind her ear. Caller would like to know for how long a person could have side effects after receiving the vaccine. The clinical outcome of little bit of pain at the injection site was recovered on 17Mar2021, tenderness and swelling like bean between the ear and the base of the jaw, feeling really hot was ongoing and feverish, there's a node was unknown.  Follow-up attempts are completed. No further information is expected.
