Can Bursitis Be Caused As A Side Effect Of Radiofrequency Ablation?

Greetings I have a question concerning radiofrequency ablation, and the link to bursitis. I recently had had a spinal radiofrequency at the L2/3 level. Which has not really gone well. I go to the pool twice a week to exercise lightly to keep my body moving. I started getting a sharp pain, and could not even rub up against anything because it was so tender to my hip. I have trouble doing any exercise, even pool is difficult at times, and since the rf, it has gotten worse. Now the doc tells me that I have bursitis. I have only had these symptoms since the RF..... Is there a connection? I cannot do much, even dishes is a real chore for me. I am in pain all the time. Please help me understand this diagnosis. the doc I have just blows me off. Thanks
