After your intra-articular injection treatment, you will notice immediate pain relief due to the local anesthetic that is injected. This will wear off in a few hours, and pain may return briefly. The steroid medication or other injected materials will take effect within a few days, and you can enjoy long-lasting pain relief at this point. The results from your intra-articular injection can last between several weeks and several months, or even as long as a few years depending on the medications injected. The exact duration of these results will vary, so we will help you determine the kind of results that you can expect during your initial visit.
