chest pain; her arm went numb; she experienced deep pain above her knees on both sides; the knees, because of clotting or whatever so she tried to rub some alcohol on her leg; This is a spontaneous report from a contactable Other Health Professional (patient, Dentist). A 84-year-old female patient received BNT162B2 (Pfizer BioNTech Covid 19 vaccine, lot number EW0167), via an unspecified route of administration at left arm on 26APR2021 at the 84 years old at single dose for COVID-19 immunization. The medical history was ongoing high blood pressure, pain and allergic.  The concomitant medications were none. The patient states she goes to the doctor for a checkup for almost 1 year but she cant go because she wasn't able to go anymore because of corona virus and she didn't go out to visit her doctor for almost one year. The patient states she has high blood pressure, but she doesn't have medicine, it was diagnosed a long time ago because the doctor said take this medicine but she wasn't able to get a checkup and wasn't able to get the medicine so she doesn't have medicine. The patient would like to report a terrible effect on herself by the Pfizer vaccine. The patient states she had her first vaccine 26APR2021 and after that she had chest pain on 27APR2021  that lasted for the next day and almost 2 days and then her arm was also numb on 27APR2021  and she just put some hot and cold compress on her chest and she just rested and it just went away, but last week the same thing, her chest became painful and she saw this number about the Covid 19 and that's why she's calling, what should she do should she get the second vaccine? The patient states she did not report to anybody yet, this is her first time. The patient states last week, it came back again and then on the next day 27APR2021, it was very deep and painful in her knees, both sides, left and right above her knees. The patient states yes, sometimes its very painful. The patient states not now, but last week the pain was in her chest and she put a cold compress on it. The patient states after the numb and pain, its not like pain, its deep pain, that's why she's bothered. The patient states it's really serious, the knees, because of clotting or whatever so she tried to rub some alcohol on her leg, that's what she did. Chest Pain; very deep and painful in her knees: The patient states it's slowly not pain, it's not very painful like before, the first and second time that it occurred. The patient states it's pain, but it's like better, it's getting better. The patient states she cannot say that it's recovered, she feels a little better. The patient confirms it is ongoing and it is persisting. The patient states it's not worsening, she just feels it sometimes then it goes away if she massage it or applies pain ointment.Chest Pain: The patient states her chest is painful, the left side of her chest is very painful. The patient states she doesn't like to receive it because she said she might be allergic because sometimes she's really allergic, but all her friends said she needs to go now, she will be protected and of course she knows that like from the flu vaccine so she searched before she was able to see and she was going to get Moderna so she said she would look for a nearer place near her and so her friend told her to go to pharmacy because she has friends there that would help her and she went there and she got the Pfizer vaccine. The patient states that's because she did not have the pain before that for a long time for many years and now after getting the vaccine, now, she experienced it.
