Hi Diane ,
The past medical history of your daughter having streptococcal infections and the present symptoms of joint pains and burning feet are suggestive of Rheumatoid arthritis . A single symptom or a single test result is not enough to diagnose arthritis . There are a number of tests that should be carried out to rule out the disease . Rheumatoid factor , ESR , Anti -CCP , ANA ( anti nuclear antibodies ) , HLA tissue typing , blood levels of uric acid , X rays of bones and joints and MRI of the joints . Please ask the rheumatologist to carry out all the tests and give a diagnosis and treatment plan if Rheumatoid arthritis is ruled out . Please take the opinions of different rheumatologists after getting the investigations results . Hope this helps you . Take care and regards !
