I have had two herceptin treatments, no chemo. I too have difficulty sleeping and staying asleep, slight cough, and some swelling of fingers. I figured all was because of the Herceptin. Good luck and hope your symptoms improve. I had Bc 10 yrs ago with lumpectamy and radiation, no chemo. Then a reoccurrence on other side in April 2006, my onc is doing herceptin and aridia. I tolerated 2nd treatment better than first, had terrible chills. Doc gave me something to counteract that problem. Have next treatment this week. Keep in touch and let me know how you are doing.
