In the normal course of wound healing, we call the first 6 weeks the "proliferative phase" meaning the period that scar tissue is deposited to heal the wounds that are created by surgical injury. This is to be expected and can be responsible for the rippling and hard nodules you feel.
Compression, scar massage, manual lymphatic drainage, and endermologie may be useful in expediting the resolution of this firm tissue druing the next pahse of wound healing (from 6 weeks up to 2 years) which we call the maturation phase.
