A 57-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number and expiration date were not reported), via an unspecified route of administration, administered in the left arm on 22Jan2021 at a single dose (at the age of 57-years-old) for COVID-19 immunisation. The patient was given the vaccine in a pharmacy/drug store. Medical history included diabetes and hypertension. There were no concomitant medications. The patient experienced arm swelling after the injection, then a little later on in the day experienced pain. The next day or so, she got bumps on the left side of the chest. Thought it was shingles and was given medicine for shingles but ended up not being shingles. She still has lumps, some were white and some have busted open, approximately 4. She still had arm pain and back. Arm was still swollen. Went back to doctor on 10Mar2021 and gave another round of antibiotics. Still has a stabbing pain from the from to the back. "1 cm to 1.5 cm." She had scheduled for a breast screening done. She was still having pain almost 2 months later. The patient provided further information: the patient only got her first dose of the vaccine. Her side effects began that day then gradually got worse. Her left arm was swollen at the injection site since 22Jan2021 and was still swollen at the time of the report. A couple of hours afterwards as the day went on, she had pain in her arm that went to her chest area. The next day (23Jan2021), she broke out with what thought as a nurse was shingles, but was just in one little spot, so she went to the doctor and gave her medicine, antibiotics, and then she took those for 7 days three times a day. The first antibiotic she was on when they thought it was shingles was azithromycin (ZITHROMAX). After then, the pain would not go away and has left scars to her left breast still, that look like white crust on them. She has pain in her left chest still from the middle to her arm down to her elbow. She has two different types of pain, and when she went back to the doctor a day before (10Mar2021), she was given more antibiotics. The pain goes from her front to the back of her shoulder blade and around and was a stabbing pain. Under her arm and going down she feels a pinching sensation that won't go away, and was all the time. They wouldn't give her the second vaccine dose while she was on antibiotics that appointment reached its due. The pharmacist came on 05Mar2021 which would be her third appointment to get the vaccine and told the pharmacist her reaction to the COVID shot. The pharmacist asked to look at her injury and then wouldn't give the vaccine to her. Her doctor gave her some pain medication that would be good for nerves. She can't take gabapentin and doesn't like to take pain pills for the nerve pain, so she does paracetamol (TYLENOL) and ibuprofen every other time to relieve the pain. She says she has been taking paracetamol 500mg extra strength twice a day by mouth, and ibuprofen 400mg twice a day by mouth. She was wondering if there was any information on if her pain would get better since she doesn't want to stay the same or for it to get worse that what it is. It was a nagging pain that she can't seem to get rid of and every once in a while she loses her grip with her left hand though not too much and she can grab again what was slipping. The gabapentin for her nerve pain gave her side effects, she was taking 300 mg one pill four times a day. She took about three days worth and starting in Feb2021 she thought. The new antibiotic given on 10Mar2021 that she takes for the bumps on her chest that won't heal up was cefdinir 300 mg. She says after her vaccine her skin blistered up like shingles centered to her left breast in the middle, which she thought originally would spread all around but it didn't, it stopped right there. She says that the spots were white and puffy, and some left a bump around in them where they healed up. She says her doctor wanted her to get a mammogram done, which is scheduled for the first Monday in Apr2021. No labs were done, "they just looked at them". The patient felt bumps on the left side of the chest was medically significant because the scars and bumps have been there a while and several were not healing well. The patient has not recovered from the events.  Information on the lot/batch number has been requested.
