Need advice!! Breast Reduction BEFORE OR AFTER SURGERY?

I am interested in looking into a breast reduction before surgery. I am 20 years old. My boobs are a 48DDD right now and I am 5'5. I know that doesn't sound too bad but I am having severe back problems because of it. I can't stand up for very long periods and that is a problem because I am trying to get a job that involves standing in the same place for long periods. I am on the right track for surgery but I am just wondering what I need to do in order to strengthen my back. I am fixing to move to Knoxville, Tennessee and my apartment complex has a fitness center and free zumba classes. I currently weigh 334.5 and I am trying to get down to at least 300 maybe 290 by the time of surgery which will be around the beginning of January. I just am unsure if having a reduction before surgery would be a good idea. I plan on getting breast implants regardless and I wasn't sure if getting the reduction out of the way would be better to do now or if I should wait until after surgery and I get to my goal? Any info would be great. Also I haven't had any kids yet and I was told that having plastic surgery before having children isn't a good idea. Thanks for any information/suggestions!

 After... When you lose weight you will most likely lose some in your chest.  Plus, any weight loss or gain WILL change the way any reduction look.   As for strengthening you back, maybe a good trainer can show you some exercises that strengthen you core 

good luck!

We have similar starting stats. My highest weight was 339 and my bra size was 50DDD. My boobs basically disappeared as i lost weight. Have you gone to a bra store for a professional fitting? The right bra can make a big difference. do you wear some sort of binder to support your back?? I would try both f these before surgery, but if your doctor recommends a reduction to help your back pain, do it now. But know you will probably need a revision after you lose weight. Good luck!!

 no i honestly dont even wear a bra anymore i did go for a professional fitting but the bras are so expsnsive i cant really afford one. what is a binder? i will look into that 

Here are a bunch on Amazon. See if you think any of these might help. I wore one when I was overweight. My back problems did go away after I lost about 100 of my 200 excess pounds.
