Well I'm 15 days post-op now and things are going well. The one thing I'm really trying to do, is resist the temptation to look at my chest too often. The only time I see it is every morning, when I have a shower, and even then, I don't study it. This is mainly to stop me obsessing over it. It's best to just leave it to get on with healing. I can feel large pieces of scar tissue. On the LHS it's near the incision. On the RHS it's spread throughout the chest. I'm not massaging yet as I think it's a bit too early, will probably wait for another week, as it's still quite tender to touch and there are still a few visible bruises.
Over the past 3 or so days< I've really noticed a huge increase in mobility. I can reach for things with more ease now. I can't extend my arms straight above my head yet, but it's close. I also (out of habit) leaned at an angle on the kitchen work surface, which involved pushing myself up (like an easy push-up). I had no pain doing this, which was interesting. But I won't be dropping to do proper push-ups anytime soon.
I'm slightly apprehensive thinking about the effect the recovery/vest will have on my first week at uni, starting monday... I'm even debating if I should stop wearing the vest during the day. It's be 5 days before Paul recommends but I'm questioning the impact it'll have (if any).
EDIT- Just a little piece of advice. I only have 1 compression vest and think it's enough. If I were you, I'd save the £40+ you'd spend on a second one and spend it on some new clothes. I wash it every couple of days, depending on how active I've been. It takes about 3 hours total, including hand wash and drying outside. So you are not without compression for very long at all.
