Is my right breast bottomed out? (photo)

I am sorry to hear about/see the problems you are having after breast augmentation surgery. I think your concerns are appropriate; your right breast implant does seem to sit low on your chest wall, consistent with breast implant displacement ("bottoming out”).
It is possible that you are feeling the implant significantly along the lower pole of the breast. Patients in your situation often complain of discomfort in the area of implant malposition. 
Generally, signs of breast implant bottoming out include: 
1. Breast implant "sits" too low on the chest wall.
2.  Excessive palpability or visibility of the breast implant along the lower breast pole.
3.  Nipple/areola complex seems to be sitting relatively high, because the breast implants have settled too low. 
4. Discomfort along the lower breast pole (secondary to pressure from the underlying implant).
5. Relative paucity of upper pole breast implant volume compared to lower pole volume.
6. Increased visibility of a infra mammary fold scar (higher on the breast mound).
I think you will likely benefit from revisionary breast surgery which will likely involve capsulorraphy ( internal suture repair).  Fat grafting is not the solution. Sometimes, depending mainly on the patient's history and physical examination, I will also use additional supportive materials such as acellular dermal matrix or biosynthetic mesh. This procedure serves to reconstruct the lower poles of the breasts and prevent migration of the breast implants too far inferiorly.  Any associated issues with positioning of nipple/areola complexes and visibility of the inframmammary fold scars should improve with this operation.There are several important "factors" involved in this type of revisionary breast surgery. Most important (in my opinion): plastic surgeon experience level.     In other words, experience level and technical expertise play the biggest role when it comes to successful  outcomes with this type of revisionary breast surgery.   Careful attention to postoperative activity limitations as well as use of appropriate postoperative support of dressing/garments are also important.
 I hope this  helps.

Based on your photos unfortunately it does appear that your breast has bottomed out.  The proper corrective measure involves revision surgery.  This should bring the nipple placement into better symmetry.

Thank you for sharing your question and photographs. I agree that your right breast implant has fallen too low on your chest and will require surgery to attempt to correct it.  This can be done with tightening of the capsule of the implant to push it higher and inward towards the breast bone, or at times requires a soft tissue reinforcement.  Seek out a second opinion for the best treatment advice.
