Post neck dissection, I experienced spectacular swelling. Here is the Hot Tip. With pads of fingers, lightly move the skin over swollen areas right and left, then up and down for a while, then move to another area and repeat. At least in my case, this produced fast results. I believe this is called lateral massage. This is just about magic! A huge and unsightly bulge above where my trach was disappeared overnight. A side benefit is that as swelling diminishes, feeling might return to previously numb areas. No promises, but this is what I experienced. Hope this helps.
