itsa4847,
Thanks for the post.
With new symptoms, it is worth getting checked out again. The most likely scenario is continued spasm with the new symptoms being different from the old becasue of the medicines you are taking. Other possibilities include having low blood pressure from the medicines (and thus leading to the dizziness), progression of coronary artery disease, onset of heart failure, esophageal spasm, among others.
Talk to your doctor, or seek a second opinion as your husband suggested. A new MRI technique has been developed to investigate coronary artery spasm, and might make sense for you as well. A large academic center will be able to do this.
Hope that helps.
