How Does A Trigger Point Injection Work?
Your doctor will place a long needle into the body that corresponds to your pain and inject steroid medication to help reduce swelling and alleviate pain.
What Happens Before, During, And After A Trigger Point Injection?
When you arrive for your procedure a clinical staff member will greet you and you will be brought into an exam room. Your doctor will greet you, explain the procedure and get your consent. You may ask any questions you may have at this time.
You be positioned appropriately for the exam. Your doctor will clean the area with an antiseptic solution and cover it with a surgical drape. Your doctor will then give you a shot of local anesthesia to numb the area. You will feel a small pinch as the anesthesia is administered.
Once the area is numb, your doctor will administer the steroid injection. Your doctor will slowly guide the needle into the area that corresponds to your pain. Once the needle is in place, your doctor will inject the medication. You will not feel pain as the needle is placed but you may feel some discomfort as the medicine is injected. This should only last a short moment and will most likely dissipate as soon as the injection is complete. Once the medicine has been administered you may feel some tingling. You should tell your doctor if you feel any sharp pain.
In most cases this procedure takes only a few minutes. Once the procedure is complete, the needle will be removed and you will have a small band-aid over the site.
You should rest for the remainder of the day but you may resume your normal activities the following day.
The injection may not have immediate pain-relieving effects but you will likely feel lessening pain over the next few days. This pain relief can last anywhere from a few days up to a few months and in some cases longer, depending on your case.
How Should I Prepare For A Trigger Point Injection?

- Your doctor may ask you to stop taking aspirin, non-steroidal anti-inflammatory drugs (NSAIDS), or blood thinners (such as Coumadin or warfarin) for a time before the procedure
