Trigger point shots are a viable option for musculoskeletal pain but I recommend exhausting other options before turning to this treatment. I have sent people for injection, but have had to find the trigger points and mark them ahead of time to make sure the correct ones were injected. Even then, the practitioner did not perform multiple passes through the trigger point or follow up with active range of motion of the muscle. I have had some patients where injections were the missing piece needed to eliminate their long standing pain. When trigger point shots are used in conjunction with many other types of treatment ( a summary can be found here ), it might be the right treatment for you if you can find a skilled practitioner in your area.
