This question is better addressed to your own surgeon.
This is one area about which there are many differing opinions among surgeons, backed by little or no scientific data. Most of us in practice were trained by surgeons who advised compression, and we have followed what we learned.
I like using compression garments primarily because they secure dressings without having to use tape on the just operated skin. Most patients find them comfortable and wear them for longer than I suggest (3 weeks or so for most). When someone calls and tells me they are uncomfortable, I would tell them to cease using the garment.
If you trust you surgeon to do your surgery, trust the post op instructions! All the best.
