Face & neck stiffness worsening 10 months post deep plane face/neck lift & upper bleph, any advice? (Photos)

10 months post op for Deep Plane Face/Neck lift and Upper Bleph. Whilst externally the results look good, my face feels tight and stiff underneath, including the skin above my eyes if I raise my eyebrows. It's like having a permanent face mask under my skin. This seems to be getting worse, not better. It's not painful, but very uncomfortable and I worry that it'll keep worsening. I consulted the surgeon 4 months post op and was advised to take Milgamma N. Any advice please?
