For nearly two years, my daughter has had deep chest pains that make her feel like her chest is in a vise. Now, she has started having muscle twitches. The doctors, after numerous testing, have been unable to determine a diagnosis. Lyrica helped at first, but is not helping much anymore. Her tests have included blood work, light down throat, heart monitor, MRI's with and without dye; sonagrams, stress tests, to no avail. Where should she go from here?
