I am 7 weeks post op, and trying to do my exercise. I went to the gym two weeks ago, did the treadmill for an 20 min, then some machines, I was very tired and a little light headed after the treadmill.
Today I went to the gym, I did 1 mile on the treadmill, drank my water and felt okay. Then I went on with my routine that I was doing pre op. Some machines and stretches. I started with 5lb hand weights, which was fine, then I did some stomach crunches. After about 30 (pre op, I did about 100), I felt a weird twing in my right side (where 1 insicion was). I stopped immediately. I then tried the chest press machine and after I was done I felt a twinge again. So I stopped for the day all together. I tried calling my dr's office, but they are closed today. I don't think it is important enough to have him paged, because it is not constant pain or discomfort.
When I got home I was going to do some laundry, and again, felt the twinge (so no laundry

), but I am concerned. Could I have done any type of damage?
What types of exercise routines do you follow?
Any advice will be appreciated.
thanks
