What does this mean?

Could be the areola itself (skin) is stretching and glandular tissue forming behind the nipple causing the pain. I think the response (sensitivity) varies between people. I felt similar for a time too. If it persists, have them looked at, I did. Yup, even had a mammogram cause it freaked me out..............thier diagnosis?, I had gynecomastia.

Do I have to go through this stage?

I'd say get used to it if you want breasts, a good friend of mine would tell me to " suck it up buttercup " so, yeah, you'll have to go through this. You've come this far right?, so don't throw in the towel.
