Yup. Had it in both arms. I had Golfer's elbow, which is inside part of your arm,elbow, Tennis is outside. Wicked painful. Went thru therapy, didn't work, cortizone shots, first set lasted 6 months, next set a few months, then they'd only last a month, think I had 6 total in each arm over 18 months. Pain was getting unbearable after dealing with this for years. Then tried a cortizone shock thing, sent electric pulses into my arm for a half hour a day 3 times a week, didn't work, tried braced and the arm band things, nada. Doc finally decided to operate to release the tendon I think. The Percosets were NICE
. Arms are better but still a little sore in the spot he did the surgery, no more shooting pain to the wrist though. Been about 8 months on left and 3 on right after surgery.
Good luck.
