Please post your two cents on Herceptin "side effects" real or perceived!

Have been experiencing shortness of breath. Also been getting hot flashes that come with a prickling feeling all over my skin....as if things are sticking me all over. Very uncomfortable. As usual, my MO says this is not a se of herceptin, but I've already been through menopause and had hot flashes with that. But never had this awful prickly feeling before I went on herceptin.
