Pain at the 5 week time frame after breast augmentation is not uncommon. Asymmetric pain (one side hurts, the other does not) is very common after breast augmentation. The anatomy of the body varies in everyone, meaning the right and left sides are different. This means that the nerve anatomy on the right may be different than on the left, which would explain, at least in part, why one side is painful and the other is not. Other factors can included sleeping habits (right side, left side) and hand dominance (right handed or left handed). You should see your surgeon to follow up on your pain even though it is likely inconsequential.
