Leftover excessive scar tissue from endo brow lift (2.5 years post op). What can be done to remove it?

Hi, I have excessive amount of leftover scar tissues in and surrounding my brows that is causing my so much discomfort and pain as well as lack of brow movement. I have tried massage therapy, taking arnica, to decrease the swelling and to encourage break down of scar tissues but they just will not budge at all. I'm in pain everyday from scar tissues pressing down on my brows. What can be done to decrease/remove these tissues? Please NO botox. too many horror stories. permanent solution only plz.
