Happy to answer this - if you've had some nodes out, it interferes with a major nerve that runs along there. You may have numbness, pins and needles or just a sensation of scrambled feedback in different parts of the area. Some or all of the feeling may come back, or there may be some permanent loss of sensation. I had my partial just before Christmas Day and that's when most of the damage seemed to happen (I didn't notice much difference when I went back to have the axillary clearance). I don't get the pins and needles sensation now but I have numbness along the back of my arm and under the armpit. Also, watch out for cording - better to get on to that sooner rather than later.
