I'm a newbie - diagnosed on Friday - and feel so happy reading your post. I am running a half marathon on Sunday (the show muct go on) and really don't want to stop running after surgery.
Ooops, I forgot to add about cycling....I found gripping and moving my arm more difficult so I wasn't confident about having to stop or move quickly because of others. The dr basically told me not to put myself in situations that would make me use reflex actions to react. I didn't swim for ages as I find chlorine very drying and wanted to look after the new skin.
Hi, we all heal differently and it depends how big and where your incision is for how it will behave when you move. I checked it out in the mirror to make sure. I was very active before treatment so at the point you are now I was getting back into it. Some of my sports bras were a better fit to keep my boob still if running. You don't want a bit of bounce making that scar any bigger than necessary. I did lots of short runs to start with, ie walking and then running a short way until I felt confident. I love aerobics classes so just didn't use that arm to stretch as I'd just get carried away and over use it. Kettlercise was by far the best class for recouperating for me, just went down a weight or didn't use one at all for that arm and I could see a huge difference each week. I did this class much longer than any other, after a mastectomy and well into chemo.
I understand where you're coming from! I'm a gym bunny and cyclist. I went back to gym very soon after, doing leg stuff first then gradually trying the arm machines.
For the bike I waited about five weeks before trying and it was hard going, I felt the strain and ache on the affected side for a while. And was having to shake my arm etc when stopped at lights.
Hopefully someone will come along with swimming experience.
