My 21 year old sister suffers from arthritis and has knee, arm, chest pain and sometimes is very fatigue. Recently she did some tests and the c-reactive protein test was very high: 26.17 mg/l. Also, the antistreptolysin test was high: 215 iu/ml.
Can anyone recommend what to do? What tests or what steps to folllow due to these high results?
Thank you very much!
