I was told that you should not have more than 4 injections in one joint per year. For example, I could have 4 sets of knee injections per year, but I could also receive injections in my back if I needed it. Frequent injections do put you at risk for osteopenia or osteoporosis though. Kera4
it depends on your age in many cases. i had about 4 in my shoulder. 1 every 8 months. i was 35 at the time. the doctor told me i was too young and i would need surgery continuing the shots even though they provided relief would hurt me in the long run. now if i was 65, it wouldn't matter much. also i think it depends on where you are getting the shot. for example the back and neck are much more serious surgeries then a knee or shoulder scope. so i think they would give you more injections there with more conservative treatment. lastly injections do weaken ligaments and cause scar tissue would could cause problems over time. but ask your doctor, he could give you better advice, also i think some injections are different? so ask.
