Hi K.Ibsen..And welcome to the forum!

It certainly sounds like you have Parkinsons symptoms..Especially the foot dragging..I had the same problem, and it was the reason why I went to my Dr..My Gen Physician mis-diagnosed me..twice..I had to get to a Nuerologist to get a proper diagnosis..and preferably a Movement Disorder Specialist..A rule of thumb..If Sinamet treats your symptoms, then you probably have pd

As for the Cymbalta..Maybe get a second opinion?..Thats all I have to offer on that subject, as I have no experience with anti-depressamts
