I currently take Metoprolol Tartrate, 25 mg, twice a day, prescribed by my Cardiologist. My Chiropractor is trying to help me with some neck spasms, and pain. I ve already had an MRI which showed some change due to arthritis, but mostly swelling in the left side of my neck where the pain is worse. While trying to adjust my spine to relieve this problem, my Chiropractor also wants to add a Holistic medication 2x/day, Formula 303, for relief of muscle spasm, tension and stress. Is there any reason for concern taking both of these medications? Her plan is to refer me to an orthopedist if, after a couple of weeks, she s unable to find me some relief.
