If you're doctor is really pushing it, it probably means you do need it. However always ask your doctor- "I'd like to avoid surgery if possible, is this necessary? What happens if I don't get it? What are the benefits if I do?". If they don't give you clear answers on that- then probably go to another surgeon.

Many times they're not pushing it because of incentives or money, but rather you came to them for help, they want to help you, and surgery is the main thing they can do to help.
