Hi A. and congrats on your decision!
You may not feel that way for a week or two, but after that! You'll be so happy!
I went from an A to a D, silicone, under the muscle. I love them. I finally have a womanly, hourglass figure and am "perky" :)
Recovery is NOT fun for the first week. I'm not sure which you're doing - over's or under's - but from what I've heard and read, recovery from the under's surgery is a lot harder. You'll feel tight - like an elephant is sitting on your chest. I suppose it makes a difference too what size you're starting out at and what size you're going to.
My one MAJOR suggestion, ICE, ICE, ICE. From the second you get home. This will keep the swelling and the pain down. I used big bags of frozen veggies, I had like 10 in the freezer. I would pile 3 or 4 on me at a time. I kept them on 24-7. My doc said it helped me heal much quicker. I had really limited bruising. I can't stress it enough. Take it EASY and ICE those new girls!
You're going to need someone there with you to help with everything. Like Debra said you really shouldn't lift your arms, and trust me, you're not going to want to, but you'll be suprised how often you normally do this throughout the day.. so having someone there to lend a hand for the first couple days is important.
I took herbal supplements to help the healing process: Arnica, quercetin, milk thistle, jeeze, I can't remember them all.
Visually .. don't freak the first time you see them! They're going to be HIGH and FIRM .. they'll settle down :) You'll be bruised, swollen .. not too pretty .. don't worry, it will pass!
I've had mine for almost a year, and they are SO different now than the first few months. I just love them (and my husband doesn't mind them at all either ;)!
Good luck!
W.
