Welcome, Cowboy 22!
You're a full-fledged member of the wrapped club! Congratulations! I had the surgery in February of this year, and have been through just what you're going through.
I do think you were pushing it to do the work you did at 2 weeks. I'd recommend you take it a bit easier for a few weeks. My surgeon said no lifting more than 10 pounds, and I would think that pushing a lawn mower, and the motion it takes to wash the car might be a bit much. I do know a member here, Rick, rode his bike something like 20 miles at the two week mark, so it doesn't mean you can't do anything. Just let your body tell you what you can handle. Listen to it!
At two weeks, your wrap is still swollen. During the healing process, my surgeon said "pretty much anything is possible". He shared the fact that until it heals, the swelling goes down completely, and things have settled into place, you can get some reflux slipping by a place where it's not sealed due to swelling. Also, I've heard that the esophagus is a "dumb organ", and it can interpret all pain/discomfort as reflux.
My pre-surgery symptoms included uncontrolled asthma. After enough time passed to allow my lungs to heal, they've been great! I also have had moments when I've gotten reflux-like symptoms--most often after having irritated my wrap by eating something too fast or eating something that was irritating. Also, there are times when my wrap gives me a little problem--a mild "pain" sensation that is solved by a small swallow of Maalox.
This surgery is a major revision of your GI tract, and it'll take time for your body to adjust. I've head that 80% of the healing occurs in the first few months, and the rest over the course of a year.
It can be deceiving, because of the laproscopic procedure--the outside of you heals very quickly, and you appear to be recovered, but the inside of you has been stirred up pretty badly, and continues to need time to heal.
As far as the shoulder pain--I found mine to be greatly relieved by walking. I went on my treadmill several times a day and (beginning slowly and building up speed and distance) I could draw a parallel between how much walking I'd done and the comfort of my shoulder. I personally think that walking is the best medicine for that problem.
I wouldn't be at all surprised that your palpatations are a result of your anxiety you have about
doing something to your wrap. I have mitral valve prolapse, and it always kicks up with stress.
I really don't think you have loosened your wrap from your exertion. You're experiencing normal healing symptoms. Still, please take it easier for a couple months. Not to say you can't do anything, but let some things go, get help, and just focus on your recovery.
There are lots of members of the "Wrapped Club" here, and I'm sure they'll be stopping by to add their perspective.
This is a great place for you to vent, ask questions, and get lots of support and encouragement.
Best wishes, and stay positive! You made a good choice, and you'll do just fine, once your body has time to adjust.
