12 months to see a hospital physio who got me in front a surgeon the next day, he wondered how I was still walking.
Same thing happened to me with my lipoma. it was 15cm in diameter by the time a GP finally referred me for surgery. The surgeon said "yeah we like to remove them when they're 5cm diameter or greater". Which was the size it was when I first saw a doctor about it.
It was about 18 months before I got surgery, when they told me it was a 6-month wait. So I'm sure you'll get seen before too long =)
