Hi Donna, the business about the wound coming undone and having problems sounds definately not normal. The tiredness is. I was blessed (or cursed) with a boss that insisted that I come to work part time about 3 weeks after I finished radiation. Even if it was just for a few hours to annoy my co-workers.
Another group of friends insisted I meet them for breakfast at 8 in the morning--the "old fart's club" The restaurant is a 15 minutes walk from my flat. Luckily down hill.
Thing is, while the group of friends and co-workers are very supportive, they also darn well meant to keep me busy and active.
Yes, even though the surgery was in Sept, the radiation ended end of Nov, I still have a stiff shoulder, some swelling and the whole side of my face neck and shoulders are numb, and about 4 in the afternoon I just run out of gas, especially on physically busy work days. But, I know if I hadn't been cajoled back to work so soon, I would have lost touch with the business, and possibly not recovered so soon.
Main thing is to get that neck wound business worked out. After that, one step at a time, but try and get John to keep moving. The law of physics applies to people also I've found "bodies in motion tend to stay in motion, bodies at rest tend to stay at rest"
