What’s the tingling sensation after forehead surgery?

These are signs of scalp reinnervation after a forehead surgery. It is called paresthesia/dysesthesia and can cause hyperalgesia/dysthermia, etc. Surely, you notice it
more in an inflamed area such as the area where the Endotines are located.

In short, the readaptation of the tissues requires plenty of time. When we speak of healing, it is not just the incision scar that is healing. All of the internal layers that have been treated and the surrounding tissue that has been detached and altered during surgery undergoes a cicatricial process of self-repair.

Symptoms such as lack of elasticity, contraction, and stiffness after FFS surgery, etc. are actually part of wound healing, which may take 2 years approximately to run its course.
