I was lifting 40lbs bag of dirt from floor onto shelf and felt pull in my back right next to...

right shoulder blade. Next morning drove 3 hours and at end right arm killing me. Now my right pinky finger and part of finger next to it are numb and have lost some strength in right hand. It has been about 7 months, have gotten some strength back but numbness basically the same. Dr. wants to do ulnar transposition. They have done x-ray and had bulging in a disk but not same location they said would affect ulnar. Had MRI but they said they did not see anything. Should I have this surgery or could the cause be somewhere else? From my understanding ulnar entrapment at elbow is from buildup
