treatment for u.n. is 2-3wks rest. there should be no symptoms above the wrist, are you pressing your elbows down or have you changed your excercises. if not better after rest seek further investigation gp/neurology. my condolences, dont think ultrasound likely to speed up recovery. ps dont take up sop sax and play squash after practicing- Im still suffering from tennis elbow 4 years after.
