Trigger point injections
I`ve been diagnosed with costochondritis and trigger point injections were suggested. What drug is used with these injections and what is the usual dosage?
Different physicians use different medications for injection:
- some use local anesthetic + steroid (cortisone-like)
- others only local anesthetic
- yet others use saline only (salt water) or dry needling (inserting the needle in and out at the trigger point site)
Most commonly used: local anesthetic + steroid. The dosage depends on the number of trigger points. Usually 1-2 milliliters of local anesthetic is used per trigger point + a varying amount of steroids not exceeding usually a total of 40 -80 mg for all the trigger points.
