Congestive heart failure; Chronic obstructive pulmonary disease; congestive heart failure and chronic obstructive pulmonary disease; Arm was killing her all the way down/her arm hurt so bad/ left leg hurts from her knee to her hip; Chills; Headache; Left leg hurts from her knee to her hip; This is a spontaneous report from a contactable consumer (patient). A 59-year-old female patient received the first dose of BNT162B2 (Lot Number: ENB207), via an unspecified route of administration, administered in right arm on 19Mar2021 08:00 AM (at the age of 59-year-old) as single dose for COVID-19 immunization. Medical history included asthma since 1990, obese since 1990, Congestive heart failure about 4 years ago in 2017, Chronic obstructive pulmonary disease since 1989; all were ongoing. She had a chemical exposure in a small town that started the COPD since about 1989. Concomitant medications were not reported. The patient previously received fluzone on unspecified date for flu vaccine and caused COPD exacerbation, she was given doxycycline and prednisone with that. The patient is calling about the Pfizer Covid 19, her first dose she received on 19Mar2021. She isn't going to take the second Covid 19 vaccine. On 19Mar2021 at 7:00PM on the day she received her Covid 19 vaccine her arm was killing her all the way down/ arm hurt so bad she wanted to cut it off. That lasted the whole next day and she took 2 Tylenol arthritis pills. Her arm was real sore the next day but it wasn't paining her like it was that first day. It was still a little sore but not like it was. The pain was down the whole arm.  Last week (on unspecified date in Mar2021), she started getting headaches and chills.  She'll get a chill and the chill will go away. Then a couple hours later the chills will come back. Her headache comes and goes. She checked her blood pressure and her blood pressure is normally low, she checked it and it was 117/76 in 2021. She knew her blood pressure wasn't causing her headaches. And she checked her oxygen level on unspecified date in 2021 and it was good. She normally does not have headaches. She's on 4L of oxygen because of congestive heart failure and chronic obstructive pulmonary disease. Her breathing has been, she can't describe it. Her doctor prescribed some steroids yesterday, 30Mar2021. She is asking if this is normal after 2 weeks. When asking her about her breathing she reports it's like her chest is tighter and she has shortness of breath. If she moves, her oxygen level on unspecified date in 2021 drops with the slightest little movement. Her oxygen has been dropping into the 70s and she has to do the pursed lips breathing to recover. It's taking a while to recover. She has to really work to get her oxygen back into the 90s. That started last week some time. She did call her doctor and her doctor prescribed prednisone and doxycycline (Prednisone 4, 10 mg tablets for 3 days, then 3 tablets for 3 days, then 2 tablets for 3 days, then 1 tablet for 3 days and Doxycline Hyclate 100mg 1 capsule twice daily for 7 days). She forgot to mention that her left leg hurts from her knee to her hip on unspecified date in 2021. That started a couple days ago. She didn't have any problems with her hip before. She's scared because the second vaccine is more potent, it's worse. She doesn't know if she's going to get that second Covid 19 vaccine. The outcome of the events was not recovered.
