hi, thank-you for providing the brief history of you. A thorough derma assessment is advised. As mentioned by you, the skin is thickened and it has no symptoms than probably the dermatologist can not help much as it is just skin hardening. for this I can advice to take therapeutic ultrasound therapy as it helps to loosen the skin by activating the cells and also by gradual stretch it can be made flexible. certain times, the hardening can be due to unknown reasons, but how the approach is made to make it flexible is important. Also, ultrasound therapy will even help to get the elastic property of the skin and kindly take help of a Physical therapist for the same. I have seen cases with scar tightness and the scar has become mobile with therapeutic ultrasound therapy. I am sure even you can get help. Since the therapy is non invasive and there are no side effects you can surely try it. keep me posted. Regards Jay Indravadan Patel
