Well guys, here's my profile: 32 year old male, fit never had problems playing tennis. However, I've been diagnosed with impingement syndrome of the right shoulder and started physiotherapy about 3 months ago. It's been helping, but my biceps tendon is still inflamed and does not respond to "conservative" treatment. Went to the doctor and he suggested me to take a cortisone shot. Has anybody taken one of those? Did it work? Please let me know. Thanks.
