Really ached all over, kind of light up a little; SED rate was up to 43; Had another SED rate down on 29th of April and then my SED rate was down to 15; Did do creatinine for muscle damage and that was high too; muscle damage and that was high too; Rheumatoid factor they did and that was high, it was 22, it should be less than 15; This is a spontaneous report from a contactable consumer or other non hcp.   A patient of unspecified age and gender received bnt162b2 (BNT162B2), dose 2 via an unspecified route of administration on 24Feb2021 (Batch/Lot Number: Unknown) as DOSE 2, SINGLE for covid-19 immunisation..The patient medical history and concomitant medications were not reported. The patient was put on prednisone (PREDNISONE), via an unspecified route of administration from an unspecified date (Batch/Lot number was not reported) to an unspecified date, for an unspecified indication. The patient experienced pain all over the body. Patient stated "I had the both Pfizer vaccines and they were on February, I think on February 3rd and February 24rd. So after the second Pfizer when it seems like I just really ached all over and it lasted a couple of days and it kind of light up a little but never really get until finally on April 14th, I did go see my medical doctor and they did put me on prednisone (suspect captured conservatively and PC Filed conservatively) because the SED rate was up to 43 and then that helped quite a bit and then I had another SED rate down on 29th of April and then my SED rate was down to 15, so they stopped prednisone. But in the meantime we had gone up to the clinic, we were 'into (voice not clear)', that's where my medical doctor was. My daughter thought we should go up there and see what they had to say and so they had said we should report this. I don't know if it is caused by the injection or not but they said no, let's just ignore anyway. So that's why I am calling today. And so I think she, the medical doctor and her Rheumatologist up at the clinic on the 2nd of July here I couldn't get in till then. So they had done a lot of lab and my SED rate is back up to 40 but they put me prednisone now but it's going to be for a month and I don't know if this kind of taper off every 2 weeks, cut it down by a half and anyway, I don't know what else, what other information you need." When probed if the consumer was taking Prednisone for Low SED rate, patient stated, "I had a high one. They said, they were looking for some formation and then they, at the clinic and they did do creatinine for muscle damage and that was high too they said and rheumatoid factor they did and that was high, it was 22, it should be less than 15. And she said that I just needed to report it to you, so I don't know what all information you need." The patient underwent lab tests and procedures which included sedimentation rate was up to 43 indicating red blood cell sedimentation rate increased, had another sedimentation rate down on 29th of april and then it was down to 15 indicating red blood cell sedimentation rate decreased, Creatinine was done for muscle damage and that was high too showed blood creatinine increased on an unspecified date and rheumatoid factor was done and that was high as well, it was 22, it should be less than 15 leading to rheumatoid factor increased. The outcome of all events was unknown.  No follow-up attempts are possible. No further information is expected..
