A 71-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), via an unspecified route of administration on 28Feb2021 at 15:00 (at the age of 71-years-old) as a single dose for COVID-19 immunization. Medical history included diabetes diagnosed 15 years ago, obesity, asthma with bronchitis as a child, allergy to other medications, anaphylactic reaction to sulfas twenty years ago (also reported as 50 years ago), muscle hurt/sore arm usually when she got a flu vaccine (unspecified) once a year, allergies to makeup and clothes (diagnosed at least 50 years ago), heart beats fast, low thyroid and borderline high cholesterol. Concomitant medications included levothyroxine sodium (SYNTHROID) taken for 30 years for low thyroid, nebivolol hydrochloride (BYSTOLIC) taken for 25 years, rosuvastatin calcium, (CRESTOR OD) taken for 2 years for borderline high cholesterol and insulin (unspecified). The patient did not receive any other vaccinations on the same day or within 4 weeks of the vaccine. The patient previously took paracetamol (TYLENOL) and diphenhydramine (BENADRYL) as pre-medication since she had allergic reactions to some things and would get this before the flu shot; as well as salbutamol sulfate (PROAIR HFA) for runny nose and coughing. The patient had the first dose of the vaccine on 28Feb2021, and "they" wanted to give her diphenhydramine (BENADRYL) after the vaccine but could not since she was driving. After the vaccination, the patient was not feeling well for 2 days (as of an unspecified date) and thought she was getting better. On 28Feb2021, the patient experienced anxiety. She was more anxious when "that stuff" appeared on the news on day 4 and 5 after the vaccine. She took a small dose of clonazepam 0.5 mg, dividing the pill in 4 pieces as she never took the whole thing. She took it when she got extremely anxious and tried not to take it because it can be habit forming. She may take it 3 times a week or in the middle of the night. It helped a little bit, but she still felt panicky and upset. She woke up feeling anxious. She did not normally take these medications. The patient reported that she experienced headache (constantly several times a week) and left arm sore at injection site, itchiness/ itching all over body (not constant but still happening) from 28Feb2021. On Mar2021 (day 4), the patient experienced dizziness (comes and goes and was not constant like it was), was very exhausted, nausea (tapered off after 2 weeks), diarrhea, some cramping in stomach, brain fog (still struggling and forgets to take her insulin, not as bad as when she first noticed), body aches. At first, the body aches were a pain in the left knee and left elbow and then moved to various joints and muscles. The left knee and elbow pain persisted without ever going away, but also moved to different areas. The calf muscle in left leg pain is also constant. The patient experienced pain in the joints and stinging pain in left leg (below knee down to ankle) from 04Mar2021, runny nose (tapered off) from 07Mar2021, and on an unspecified date muscle pain, back pain, fever, neck pain, pain in left arm. On Mar2021 (two weeks after vaccination), the patient had a red circle around injection site not all the way filled in, but rim around where she got shot. On Mar2021 (3 weeks after vaccination), the patient experienced a weak feeling in arms and legs and other times when she stood up her body felt heavy (persistent but not every day). The patient spoke with her physician who did not believe the patient about the symptoms and recommended she seek psychiatric help. The patient had not received the second dose of the vaccine because her physician did not recommend it. She was upset because her physician told her she could not get the second shot. She was having worsening anxiety because she had not been feeling well for so long, going on 7 weeks. She visited her physician's office 6,7, or 8 times. The patient underwent lab tests and procedures on unspecified dates which included an ultrasound of the leg (did not have a blood clot), an X-Ray of the back (unknown results) and an MRI of the back (did not find anything) to determine the pain. The physician thought it might be a compression fracture, but the MRI did not show anything. The patient was tested for antibodies on 05Apr2021 and had zero antibodies. The clinical outcome of anxiety, felt panicky, neck pain was unknown; dizziness, headache, runny nose, itchiness, pain in the joints, muscle pain, back pain, fever, very exhausted, nausea, diarrhea, some cramping in stomach, brain fog, body aches, stinging pain in left leg / pain in left arm, weak feelings in arms and legs, body feels heavy, left arm sore at injection site, red circle around injection site, not feeling well,  was resolving.   No follow-up attempts are needed. Information on lot/batch cannot be obtained.; Sender's Comments: Linked Report(s): same patient, different vaccine dose/event
