I had juvederm filler put in my upper lip two and half years ago. I did not like it and figured it would go away in about a year. I have several medium sized, clear, blister like bumps all across my lip. They are semi hard and have no pain. I can not whistle or close my lips all they way. I went to a board certified surgeon. At first I thought it was the juvederm, but it's been too long. What may have happened?
