Thanks Gingernut!
My GP has known me for over 20 years, knows I am strong as an ox and said there is nothing like the motivation of a self employed person with bills to pay when it comes to recovery time
My main worry for any operation is being Factor IX deficient but hopefully the haemotologist has that under control. Took so much blood last week I'm surprised I had enough left to make a massive bruise at the site they took the blood from
