I’m about a month or so into mine. Mine has healed quite significantly but it’s still gonna be a while for me to have it on. It smells awful and you may get sick of it, so I do use my wound vac bag in perfume/febreeze to help cover it. I’ve heard people having the vac on from anywhere as little as 3 weeks to 3 months, it just depends on how extensive your procedure was and how fast you heal since everybody heals differently. It also depends on how well of a seal you can keep there because a good seal = quicker healing, a leak = slower healing and possibility of infection if not corrected.
Had my first dressing change on Tuesday wound was very clean, no smell at all,minimal cleaning was required with saline water solution, the only smell was in the wound vac where it collects the drained liquids from
the wound but this gets changed as well when you change the dressing along with the tube connected to your wound and the wound vac. My doctor has not advised a definitive time frame for how long it will be in for they will keep checking the progress of the wound at every dressing change and decide once there has been enough progress to discontinue usage. When they change the dressing it is painful however the pain subsides once they are done.
Much better option to have the wound vac as your dressing does not need to be changed daily.
fyi I didn't have my surgery with him, but considering hes only specialist posting on this forum, gotta give him credit for that. And I've read a lot of people say good things about him and his staff as well.
