I want to share something that worked for me. A couple of weeks ago I was discouraged about how much discoloration my totally healed incision still had around it. I had zero bruising with my first knee and I really was sad that knee number 2 looked so bad at 6 weeks. Somewhere here I read about Arnica Gel, so I bought some. I was not impressed when I rubbed it on my knee that night. Odorless, colorless, disappeared into my skin like nothing. But I had paid my $8 or so, and was determined to get my money's worth. Applied it morning and night, and it actually worked! I could tell the difference about three days out, and after a week my knee looked great!
