Will I need to prepare for the trigger point injections?
The trigger points are injected in the doctor’s office, and no sedative
or local anesthetic is used. The procedure is done with you lying face-down

notify the doctor if you are taking anything that thins the blood. This
include nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, Coumadin,
Plavix, and Ticlid.
How are trigger point injections done?
After you meet with the pain management specialist, the doctor will evaluate
you and decide if trigger point injections will help. The nurse will go
over procedure risks and benefits, have you sign a consent form, and make
you put on a procedure gown. The doctor will clean the skin with an antiseptic
and palpate the trigger points. After identifying all the regions, the
skin is marked with a skin pen. The doctor then injects the region with
a tiny needle, instilling the medication. Small spot Band-Aids are applied
to injection sites.
What can I expect after the TPIs?
After the doctor injects your trigger points, you may experience some mild
bruising and tenderness at the multiple injection sites. Over the next
few hours and days, you will experience pain relief. If a corticosteroid
is used, the anti-inflammatory effects will not be noticed for 2-3 days.

found that the therapy reduce pain and improved shoulder function. In
a study where patients with fibromyalgia were treated using TPIs, doctors
found that the injections improved quality of life and range of motion.

migraine, and cluster headaches with success.
