I fell 8 months ago at work and fractured my right patella. Spent five months in brace and crutches. Have been going to physical therapy for four months. I was using right arm to brace whenever I got up from sitting and other movements. The last month or so I have had pain and soreness in right elbow sometimes radiating into shoulder. Is this tendonitis and does it go into the shoulder area? Thank you in advance for any info on this.
