Chronic RUQ pain

Katie;
I may have an answer to why this happens after having operated on a patient who actually had the spasm while in a CT scanner and was misdiagnosed as having a tumor. At surgery there was a thickened nerve coming through the connective tissue, supplying the area of muscle that was spasming. I cut the nerve and the patient has had no further problems. A chemical nerve ablation may solve your problem.

Good luck,
Steve Goldstein
