Thinking about surgery, is it worth it?

I need you people who have had surgeries to be real with me. I’m 21 now, pretty much at stage 3. Yes, I’m very scared of the idea of having my body cut open, conscious or unconscious. I’m scared of the pain. But I’m in a lot more pain now and emotionally tired of the odour. Do the flare ups come back, even if you tried to cut out your “trigger foods”? How has your surgery affected you physically and emotionally? Do you find that your quality of life improved? Healing time? Can you lift your arms? Pain? I’m sorry I have so many questions but I am very anxious. My doctor encourages surgery but he’s only a doctor. I want to know what I’ll experience when I leave the hospital.
