If you decide to go with a subpectoral pocket and your surgeon does not dissect it too far close to your sternum you should be safe. Chose a skilled and board certified surgeon who has experience in Breast augmentation to avoid such issues.
I recommend that you arrange a follow up with your surgeon and have him remove the dressing and inspect the wound to reassure you about how things are healing.
The concept of injecting steroids in the nose is unsafe for the type of procedure you had. I am glad that your surgeon is not attempting that. There might be many explanations for your swelling.To be able to better answer your question I would recommend posting a close up photos of the nose from the lateral view, front as well as both bird eyes and worms eyes view to be able to assess the deformity and advice you on the best course of action.
You need to see a board certified Plastic Surgeon with experience in Breast augmentation, correcting your breast problem should begin with assessing the degree of ptosis (breast droopiness) , and wether you would be a candidate for a breast lift . Sometimes the problem is better corrected with a mastopexy procedure to improve the shape and projection of your breast. Talk to your surgeon about the different techniques available. If the suggestion is made to replace the implants with larger ones alone inorder to address ptosis, I would recommend getting another opinion as most of the time when ptosis is corrected in revision of breast augmentation with larger implants, patients end up with a high risk for recurrent Ptosis and usually return back to their surgeons dissatisfied because this procedure usually does not address the real issue, which is increased skin laxity (loose skin and gravity effect).
