Why Is Aspirin a Contraindication for Trigger-Point Injections?
Am Fam Physician. 2003 Jan 1;67(1):32.
to the editor: In the article entitled, “Trigger Points: Diagnosis and Management,”1 Table 3 lists aspirin therapy as a contraindication to trigger-point injections. Given the current recommendations for aspirin therapy to prevent coronary artery disease events, large portions of the adult population in the United States are currently taking or should be taking aspirin on a regular basis. If aspirin therapy is truly a contraindication to trigger-point injections, then trigger-point injections would be off limits to a large percentage of the adult population.
The only information presented in the article to support this contraindication is the citation of two textbook chapters.2,3 What evidence, if any, indicates that trigger-point injections are dangerous to patients taking aspirin?
