If during the past two months, the itching and tightness seems to have been resolving, then YES, those issues should continue to improve with passage of time. If not, then it is recommended that you contact your surgeon and/or schedule follow up appointment. Tightness may be remaining induration (dense tissue related to healing process), impending scar extrusion, or other issue. Itching may be a skin sensitivity to something you're applying, may be from disturbance of sensory nerves in area of lip lift, or may be something else. It's hard to know without having more information about your exact situation. Again, if these problems are not improving, contact your doctor to ask directly.
