Aching joints. See your doctor or a cardiologist ASAP to rule out the possibility of rheumatic fever.
See your doctor. You might want to go and be re-examined by your doctor so he or she can rule out rheumatic fever which can cause joint pain, heart problems, and a rash among other symptoms. This is caused by the strep bacteria and you may not be on the proper antibiotic. .
