I had arm discomfort the day after the injection but it has now settled. My partner - injected the same day - has swelling, redness and discomfort around the injection site - some call it Covid arm - this usually occurs after the Moderna vaccine but it can occur with Pfizer. Simple painkillers and an antihistamine are the suggested treatments, if anything is needed at all.
