Hey jojo Ive from the UK too and had surgery with Rahal in April. Quick note about the sututres, there not as easy to remove as made out, i had black hair and the sutures were black too making it vey difficult to locate. I made an appointment with a nurse at my local surgery who made an attemtp to remove the sutures but couldnt (she said she hadnt seen any sutures like that before and she looked quite experienced) Ended up having to go to A&E who removed them, but i doubt you could, even if you could see the back of your head with a mirror lol
Just some info for you as a side note, i stayed 5 days, flew in straight to consultation, next day surgery, 4 nights later back on a plane to london. theres no need to stay there much more than that.
