Well phoned my GP on Friday and the receptionist said my full blood count and renal profile were both normal. I wish I had asked for the actual numbers for the kidney function test though as my GP told me that what was considered outside the normal range at Guys was considered normal by Lewisham and my blood tests were done by Lewisham....
Old Sheep, I think you must live close to me as I see from your posts that you cycle in Greenwich Park. I used to do that, going down was great but not so easy coming back up!
