People experience pain differently, but for most guys Top Surgery causes low to moderate post-op pain. Your surgeon will provide with you information about recovery. I found the drains a bit painful and iced the incisions where they entered to provide relief. I kicked the codeine within a couple of days of surgery because I didn't like how it made me feel, and switched to Tylenol which worked fine. Don't hold off on pain pills if they're needed though: it's harder on your body to heal in pain. I also took Arnica to minimize bruising, to great effect. Hope this helps!
