My 10-year Old Was Diagnosed With Strep Throat Yesterday And

My 10-year old was diagnosed with strep throat yesterday and was prescribed Amoxycillin x 10 days. Today she is complaining that her wrists and her big toes on both feet hurt. They hurt when she is just sitting down, as well as when she walks. She has pain if you touch her toes. Are these symptoms related to the step throat?
