Torn biceps tendon 7 weeks ago playing softball. had ultrasound, awaiting mri sept 15. should i exercise to strengthen or wait for mri & specialist.

Wait: You should always wait for your doctor to give you the "a ok" before doing anything while having these conditions, you don't want to make it worse so i would wait and take it easy until your doctor lets you know what you can and can't do :].

See ortho now: If the tendon is completely torn there is a limited time in which in can be reattached. I am not an orthopedist but i recommend you consult one sooner rather than later because this may be a time sensitive issue. In the meantime range of motion exercise is all i would recommend because you dont want to convert a partial tear to a complete tear.
