History Of Broken Bones. Difficulty Bending Fingers After Cast Removal. More Surgery Possible?

I am a 72 year old woman who fell at home and broke my right upper radial head on June 21, went to the hospital where a temporary cast was put on with instructions to make an appointment with an orthopedist the following Monday. I could not find an orthopedic surgeon who worked on the elbow who could take me then, but was finally seen by one a week later on the 27th. I was operated on and ligaments were stretched to hold the broken bone in place. Since the cast was removed and I have been in therapy , my wrist and fingers are frequently swollen, and am having great difficulty bending my fingers. Have yet to make a fist, although I can pinch my index finger and thumb , as well as the other fingers even though it is very painful. My orthopedic doctor took an xray of my wrist a week ago and found no break, and simply ordered more therapy. I can not straighten my right arm out completely, but have made progress being able to reach up to my left shoulder. I wondered if I need to be re-evaluated by another doctor, and possibly to have more surgery if it can eliminate this pain and restricted movement. thank you
