15 yr old athletic daughter is having sharp pains right side below ribs & rt upper arm pains difficulty using arm started infrequent & now daily lasting 10min to hours. NOT heart or asthma as all tests (echo, stress & pulminary) show extremely healthy. Bloodwork normal so next step abdominal ultrasound for gallbladder. Any suggestions? Just using Aleve right now but this is ridiculous that its not something obvious.
