Contracture is not going to present this early. It doesn't meant that it won't present at all, nor does it mean that if the pocket is tight there is a higher incidence of it presenting. All it means is that your implant is larger than the pocket that was made for it so it feels tight. In time, your implants will stretch out the inner tissues and make room. Then you should feel them soften (that can take up to about 3 months).
In some patients this is necessary particularly if the size difference is really big (going from a AA to a D for example). Those patients are all going to feel the pocket tight. It is also possible that the pocket needs some time to stretch because it's smaller than the implant (even if your growth isn't as drastic as the cup sizes mentioned above).
In either case, it has nothing to do with the bandaid situation. Your nipple sensitivity and tight pocket sensation are both likely due to the same source. The implants are large and they are stretching your nerves; that is irritating them some. In time, everything should adjust and get better. You should keep your doctor very informed of this problem because there are some measures that could help make the process resolve a bit faster.
