Soccertese, the swallowing problem after DBS is a well-known side-effect and not just specific to Boston Scientific, it applies to Medtronic as well (many refs in the literature). As I mentioned, it can sometimes be improved with proper programming, but that takes a while to get it just right. Often it apparently involves over-stimulation to correct tremor, but it's that balance between motor problems & side effects that I referred to above. May be a trade-off required. I'm still hoping it may be improved & have another programming session scheduled for next month.
