Interventional Pain Management

Pullman Regional Interventional Pain Management

If pain interferes with your daily life and cannot be managed through prescribed medication or therapies, interventional pain management may be able to help. Pullman Regional Interventional Pain Management offers non-surgical pain management services to help diagnose and treat chronic pain. Interventional pain management involves using procedures to block and/or treat the source of your pain, rather than through prescribed medications. Therapies and procedures are performed on an outpatient basis.
A referral from your primary care provider or specialist is needed to access Pullman Regional Interventional Pain Management services. Pullman Regional Interventional Pain Management does not prescribe or stock medications, including opioids. 
Pullman Regional Interventional Pain Management is staffed by Pullman Anesthesia, a group that has been practicing on the Palouse for over 30 years. Pullman Anesthesia is a member of the Society of Opioid Free Anesthesia (SOFA) and provides surgical and obstetrics anesthesia services to Pullman Regional Hospital.


If you are experiencing a life-threatening emergency, please call 911 or go to the nearest emergency room.

Trigger Point Injections involve inserting a thin needle attached to a syringe into the trigger point and rhythmically needling the area by inserting and retracting the needle repetitively. The muscle will likely spasm or twitch. This is continued in multiple directions until the muscle twitching has stopped or until the muscle feels adequately relaxed.

Coccydynia is pain in and around the bony structure at the bottom of the spine, called the coccyx.

If you're scheduled for a total knee replacement surgery, ask your orthopedic surgeon if you would be a good candidate for Iovera Cryoneurolysis.
