Arm tuck surgery??

I’ve lost 100lbs in a year and a half, I’m planning on losing 50 more. My stomach skin doesn’t bother me, I actually have thick skin so I should be able to tone that up fairly well...however...I HATE my arm flaps. I’m so self conscious of them and can’t bring myself to wear any sleeveless shirts. Has anyone here had arm tuck surgery? Is it worth it? Is it really painful? Any advice would be greatly appreciated!
