I think it’s 6 weeks that you have to wear your post surgery bra. I had my op yersterday and I have got to have strapping on until my post op appointment next Friday, and then change into my sports bra which I think I have to wear for 6 weeks, my surgeon doesn’t like Macom bras so I just have a post operative m&s high impact sports bra. You will find out when your allowed to stop wearing your sports/Macom bras at one of your post op meetings, your nurse will tell you when you can stop wearing them xx
