Sheepdog,
I also have noticed the return of my PVCs since I got off all beta blockers. I had to due to the debilitating side-effects. The PVCs are very mild and infrequent. I don't get trigemeny or any of the other more complicated arhythmias anymore. I can still feel every one of them, though. It was such a feeling that warned me 12/9/07 that something was wrong. When I got 20 powerful PVCs in a row, I felt every one of them--the rest is history. That was abnormal, but that funny squirmy feeling I get with singles I generally forget about them since they're isolated.
As for the left vs right side laying down, it's true that the heavy liver is on the right side, and can shift a bit. It's also true that our hearts point to the left and our left ventricle (of course) is there and is the first to encounter ribcage when our liver, pancreas, stomach, etc. shift. People with mitral valve prolapse also notice increased PVCs when on their left sides more than right. Now post surgery I don't notice as much difference in frequency, but they seem louder and more intense when I'm on my left. In general my internal sense of my heartbeat is stronger when I'm on my left as well, but I can still sleep on my left side.
I guess some of us still have touchy hearts that have minds of their own and send 'protest' signals to us in the form of PVCs as if saying "Hey! I'm being squashed here--roll over will-ya!" Or "Watch those bloating foods! I need some beating room here!"
Speaking of being squashed, I managed my healing shoulder and back pain by lots of chest and arm stretches. I read about contractures that people get from being afraid to straighten up post surgery and didn't want that to happen to me. I was getting a keloid and, even if it hurt, I didn't want it to keep me hunched over the rest of my life. So I did something that would make a chiropractor wince. I would find a nice flat door opening or some other fairly narrow (as in 2 x 4 width; about 3-4 inches wide) vertical flat smooth surface. I'd line myself up with my shoulder blades spread, and with as good posture as my condition would allow, I'd firmly smack my back against said vertical surface. I'd do it two or three times until I'd feel my misaligned vertebrae sort of crunch back into position. Almost immediately my pain would lessen. This had been a problem when I was about 3-5 weeks post surgery. I first had to do it sometimes several times a day, then just once daily, then every few days, and now almost never have to do it. I also lay down on my bed on my back and did away with the pillows for as long as I could stand it--the pillows of course were there for sleeping, though. Later (about 7 weeks onward) I frequently lay on my back with my head actually hanging down off the end of my bed. Kept up the stretching exercises, etc. The result? The best posture of my life.
I'll pray that the Lord helps you with the back, PVCs, and emotional stuff post surgery. I needed (and still need) lots of prayer to get me through the immediate post surgical time and the half year since then, and I suspect you will likewise. You can count on us to do it--it takes someone who has truly been there to really understand how to pray for help for you.
