My 16 year old daughter is experiencing pain in her her upper left arm. She has not injured it or over used it. She reports that it feels like someone punched her. She recently, four days ago, started on birth control...generes FE...due to horrible menstrual cycle and pre -menstrual terrible anxiety. In addition, she had a strep infection in her stomach...severely nauseated... not throat pain...about two weeks ago. She finished her antibiotic and the strep infection has cleared...checked again today. She also has been experiencing extremely high levels of anxiety...debilitating/like never before...since the strep infection. We are working with her pediatrician, OB/gyn to try to help. Everyday is unpredictable. Any suggestions.
