What you’re describing is actually quite common during the healing process. The firmness is usually caused by internal swelling, scar tissue, and the body’s natural response to trauma in the treated areas. This hardness can persist for several weeks, even up to a few months, and gradually softens over time.
The soreness can also be a part of normal nerve regeneration and tissue repair. That said, if the pain is sharp, getting worse, or accompanied by heat, redness, or other signs of infection, it’s important to check in with your surgeon. Otherwise, gentle massage, staying hydrated, and continuing any post-op care instructions (like wearing compression garments) can help improve the healing process.
