Hi Catherine of Oregon
I don't think you are crazy, selfish, or paranoid. You are experiencing what happens to all of us when we get near the end of our treatments. Some people describe it as "getting thrown off a cliff". I thought I would be very happy to finish all of my treatments, but I wasn't. While on treatments, we feel like we are fighting the beast; when they end, we move on to check-ups and sometimes blood tests and scans. It is "normal" to be wondering about every ache and pain. That's what "we" do now....it is the new normal.
Your aches and pains all over could be from the herceptin, arthritis, a virus, the weather, tamoxafin, an A.I. etc. I think there is a general rule about waiting a week or two and if you still have the pain, get it checked out by a doc.
Or you can go back and read the Tiptoe thread and laugh the pain away...or eat some chocolate
