A 82-years-old non-pregnant female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Lot Number: eL9264), dose 2 via an unspecified route of administration, administered in arm left on 12Feb2021 (at the age of 82-years-old) as dose 2, single for COVID-19 immunisation. Medical history included breast cancer, asthma, mastectomy (and lymph nodes removed on both sides, 27 lymph nodes removed on one side and 17 or more on the other side), neuralgia (across her chest), deaf (uses a special phone that helps her hear and that she can read what is being said on while on a phone call), tricuspid valve disease, pacemaker lead impingement on tricuspid leaflet and lymphedema (which has been bearable, however early on it was horrible, this got better with years). The patient was allergic to Penicillin and all dilation meds like Sudafed. The patient's concomitant medications were not reported. The patient previously received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Lot number: eK9231) administered in arm left on 22Jan2021 (at the age of 82-years-old) for COVID-19 immunization. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. Prior to vaccination, the patient was not diagnosed with COVID-19. Since the vaccination, the patient has not been tested for COVID-19. On 01Mar2021, the patient experienced severe armpit pain/having a number 7 pain because it is so extensive in both armpits across her chest/extreme burning pain in both armpits and across my chest, across her chest it is burning/having a number 7 pain because it is so extensive in both armpits across her chest/extreme burning pain in both armpits and across my chest and swelling. On an unspecified date, the patient experienced she thinks her blood pressure is up, felt a little low, tired, swelling and flares for her lymphedema. The patient reported that she had both doses of the vaccine and had a medical history of lots of lymph nodes removed on both sides and a double mastectomy. She was a breast cancer survivor over 40 years ago. She reported everything seemed ok, she was a little tired but not much. She reported that she did not notice any pain right after the shot but starting about 5 days ago she started to have severe armpit pain on both sides, which she had the shot in her left arm because she has been having shots previously and was not worried about it, for many years she has had injections. Across her chest it is burning. She was wondering if her history and the nerve damage from the surgery was the reason that was happening. She had the first vaccine and hardly noticed anything and after the second dose felt a little low for a day or two but that was it (and that was 12Feb2021). 5 days ago, she was having a number 7 pain because it is so extensive in both armpits across her chest. She did not have a fever but all she had really was pain, so she called about having bad nerve pain, which nerve pain was never nice. "She thinks her blood pressure is up". She takes a lot of medication so she thought it could be a combination of that too. The doctor told other patients have been reporting various aches and pains including back and shoulder aches and pains. She asked if there was any information on someone who had a double mastectomy or lymph nodes removed and then had a flare of these symptoms after the vaccine. She asked if this could be related to the vaccine with the symptoms being delayed this much. She felt that was important because she did not want to overreact if it was from the vaccine, and if it was an expected reaction for mastectomy patients who lost lymph nodes and had nerve damage like the thoracic nerve nicked or something. She would like to know if it was an expected reaction with someone with her history. She thought it was weird, and wanted to know if that happens, a delayed response like that. She stated it was important because she did not know what was going on, she used to call it flares for her lymphedema, and she has not had one in so long. She thought it was okay to wait a week more to do anything since she already spoke with her HCP. The adverse events armpit pain, chest burning pain of and swelling resulted in doctor or other healthcare professional office/clinic visit. The patient did not receive treatment for the events armpit pain, chest burning pain of and swelling. The outcome of the events armpit pain, chest burning pain of and swelling was not resolved, and for the rest of the events was unknown.  No follow up attempts are possible. No further information is expected.
