I feel like my left implant / breast is dropping faster than my right. + Odor after axillary approach (Photo)

I am 3 weeks post-op (300 cc silicone) & still wearing my compression band for a few hours a day.My left breast seems to be appearing larger and lower as its dropping faster than my right. Procedure was done with axillary approach. Now I am back to my normal routine, but i have a bad odor coming from my armpits which i never had prior to surgery. I do use deodorant and wash it with antibacterial soap but the odor comes back within the next 20 min. Stitches seem to be healed fine & no infections.
