Thanks everyone. I will call the doctor's office Monday. So far its only happened three times. All three times it happened just as I released pressure from my under arm. I'll keep you posted.
bvdr, I'm actually doing quite well. My appetite is ravenous right now LOL! My weight is steady at about 200 which is perfect. Pre-surgery, I was 215. A target weight of 195 would be nice, but I'm not going to try to push that. I'm not sleeping near as much as I thought I would. A lot of people say 'do what your body tells you' and so far, I've had no desire to sleep during the day. After long walks or activities, I do feel a bit down, but not necessarily tired. It almost feels like I've been working out all day without eating anything. Kind of a weak, lethargic feeling. At that point I generally sit down and watch TV or go online until I get my energy back. My sleep at night is getting better. I'm able to sleep in my normal positions without too much discomfort. This morning when I woke up, it was the first time since that I felt good. All other mornings have been terrible. It's clear I was getting fitful sleep and hopefully that is going away. All in all, I completely expected something different for recovery. I was prepared to be bed-ridden for 2 weeks with periods of getting up and walking. It really the other way around. I'm up with periods of rest. I'm still having problems with not being able to lift anything. Very frustrating watching my wife haul a 30 lbs bag of dog food in while I sit there eating ice-cream. I started to get up and she told me to 'sit my butt back down' LOL!
