Tweeti personally don't think the difference is that big... i didn't even notice it till u pointed it out...
as for ur questions, i don't think antiinflammatories would do anything for it... it's not an inflammation...
i would go for the surgery... true it might look smaller, but it also might not... even if it does, it's really easy to grow tits again...
i got gyno too, and the only way i could hide it, was by increasing my upper chest size... it does the trick but i still got gyno...
i tried 'hitting the gym and dropping the bf' and it didn't change my tits at all...
so if u ask me, i'd go for the surgery.....
