I am bottoming out. Will internal sutures fix this even though I want to go up in size? (photo)

I am sorry to hear about/see the problems you are having after breast augmentation surgery. I think your concerns are appropriate; your breast implants do seem to sit quite low on your chest wall, consistent with breast implant displacement ("bottoming out”).
It is probable that you are feeling the implants significantly along the lower poles of the breasts. Patients in your situation often complain of discomfort in the area of implant malposition. Also, consistent with the breast implant positioning problem, the nipple areola complexes seem to be sitting relatively high, because the breast implants have settled too low. 
I think you will benefit from revisionary breast surgery which will likely involve capsulorraphy ( internal suture repair). This procedure serves to reconstruct the lower poles of the breasts and prevent migration of the breast implants too far inferiorly. Associated issues with positioning of nipple/areola complexes and any visibility of the inframmammary fold scars should improve with this operation.
Make sure that the plastic surgeon who does this procedure for you can demonstrate significant experience with revisionary breast surgery.
I hope this, and the attached link, helps.

Yes I see the "bottoming out... Best to either internal suture cappsularraphy or ACDM implantation or both. Increasing size could cause the issue to return...

Based on your information, this does not seem like a good solution. Internal sutures do work but placing larger implants may have the opposite result.
