sorry you're dealing with this. i definitely would have these new symptoms checked out. there may be some cause/effect between the strep and the swollen painful joints or you may have developed something else entirely. at any rate the sudden onset of the symptoms you describe in an otherwise healthy young female is reason enough to seek medical care right away. your best bet is to return to the urgent care facility where you received the strep test and injection because they'll have your medical records at hand. normally i wouldn't advise someone who believes they have strep throat to seek urgent care. it's something that can be handled by a primary care provider. take care and best wishes!
can a strep throat that was trated with antibiotics cause joint pain and swelling? . 29 year old female with sudden onset of swelling and painful joints. 2 weeks ago had strep throat treated with a shot in the urgent care center.
