It sounds like the mark from the blade cut has been a concern for you. Over time, scars can change in appearance; they may become raised, discolored, or itchy due to natural healing processes. To address this, options include topical treatments, laser therapy, or surgical removal, depending on the scar's characteristics. I strongly encourage you to consult with a dermatologist who can assess your situation and recommend the best course of action tailored to your needs. Professional evaluation ensures safe and effective care, helping you achieve the desired results.
