Stellate ganglion blocks can offer pain relief that last for several weeks in many patients, but the total timeline for which the results can be enjoyed varies quite a bit from patient to patient. It is common for patients to need multiple injections of the SGB in order to have longer-lasting pain relief, but the total amount of injections that they will need each time differs quite a bit, ranging anywhere from 2 to 10 injections required. Many patients will also find that the relief from pain will last a bit longer each time they receive treatment, so the first treatment will often offer the shortest lasting results. For longer-term pain relief, many physicians will recommend that patients receive another block every 1 to 2 weeks and after a series of blocks, the pain relief will be much longer-lasting.
