How long to return to camping after open heart surgery

I haven't had heart surgery, but had a surprise surgery for an arterial clot in my leg. That kept me down for a bit.
It can be hard to deal with what feels like a slow recovery, I dealt with that during chemo for chronic leukemia. My advice is look at your recovery like eating an elephant- one bite at a time. Set reasonable goals that you can accomplish so you can see your improvement. And you will see improvement.
