If you have osteoarthritis
, the injection is technically more difficult and may be more uncomfortable. A bursitis injection can easily be done in the doctor's office while an intra-articular injection (for osteoarthritis) is often given under x-ray guidance. The response to both may be variable: anything from complete, long-term relief to nothing. The response to injection depends on the accuracy of the diagnosis as well as the efficacy of other concurrent treatment strategies such as activity modification and physical therapy
, with suspected bursitis, it is important to evaluate the low back to make sure that the hip pain
isn't referred from a bulging disc or sciatica
With injections in the joint, there may be some accelerated cartilage
breakdown secondary to effects of the corticosteroid. The duration of relief, if any, tends to be shorter for these injections as well. There are fewer risks with injections in the bursa. However, if multiple injections are required, there is some concern about the cummulative effects of the corticosteroid that is absorbed in the system and there is probably a reason to look at other treatment options.
