I decided to have this procedure done because while my dad was fighting Leukemia I forgot about my Health and plummeted to 140 pounds not so bad but in almost 6 feet tall, I gained tear throughs and started noticing them and was devastated. No one mentioned them but I noticed them. I went to Halifax nS and had them filled by a lovely lady, she sed a cannula and it didn't even hurt:) I had a bit of swelling but nothin serious! I totally recommend this procedure, but don't worry when you swell, you probably will. It will go away:).
