THR-minus16 days!!

Hello, a bit about me first, and how I got to here!!
I am 40 yrs old, married to Steve, with 3 daughters aged 12, 14 and 16.  I work as a Personnel Manager in a Supermarket.
As a 10 yr old I had a slip and ended up with a Slipped Upper Femur Epiphysis on the Left hip, which had 3 pins put into it, then 6 months later the right hip joined in too!!  So, I had that operated on as well.  The pins were removed a year or so later, end of story...... move on several years to my first pregnancy, I suffered a lot of hip pain during my pregnancy, I had to be carried up the stairs as it was so bad, not an easy task when you're 8 months gone, 14 stone and hubby's 10 stone nothing!! :-).  I then had episodes of pain every now and again, nothing horrendously bad, but caused discomfort and interferred with living my life a bit.

Back in January I decided that I could take no more, it was really getting in the way of living my life and working.  I went to my GP who hastily ordered some Xrays, they showed 'changes' in the shape of the joint, he gave me a steroid injection into the side of the hip, which he said 'could' settle it down for a few years...it didn't!! 
So the doc's next move was to refer me to an Orthopedic Surgeon, as he said with my history there was a very good chance that I would need a THR.  I am fortunate enough to have Private Health Care as a 'perk' of my job, so I was referred to a very good chap who specialises in young hip replacements (pre 50's).
He examined me and ordered, a MRI-A, plus a Hip Block (to decipher if the pain is coming from the joint) and a Cortisone injection into the joint space.
All these were completed the following week, a gerat example of how quickly private medicine works, you might think!! The MRI-A was a weird experience, it felt like my thigh was being blown up like a balloon, I could barely walk after it, but within 3 hours I was back to normal.  Two days later I had the hip block, and cortisone injection, the hip block worked like a dream for 5 hours, then I wanted to die!!  I was in agony for 24 hours, could only walk using a stick.  After that it was a little better.  Following that I went on holiday for 10 days (I gave up smoking during that holiday :-0) and was told to ring the OS when I returned with how I had got on with the hip block and the cortisone.  It did improve for my holiday a bit, but soon after I got home it went back to how it had been before.
It was 9 weeks after my MRI that I finally got a follow up appointment (9WEEKS!!!!That's PRIVATE!!) during those 9 weeks, I rang the clinic twice every week, I was quite distraught!!  Anyhow, the OS referred me to another OS who specialised in Hip Resurfacing as he thought that may be an option for me.
I went to see OS no.2, he was lovely, he told me that I have Femoral Acetabular Impingement (FAI for short), a torn labrum and 3 cysts in the bone.  He suggested arthroscopic surgery, which is keyhole, going in and repairing the torn labrum, cleaning up the cysts and shaving down the bony growth which was causing the impingement.  He was clear though, that he could only recommend this if the arthritis in the joint was mild, so ordered a 3D CT scan to check the levels.
The report on the 3D CT scan came back as moderate arthritis, the arthroscopic surgery doesn't have a wonderful success rate in the best of circumstances, but with moderate arthritis, the OS no.2 said that if I went ahead with it I would still need a THR within 2 years, so it would be a pretty pointless exercise.  So he decided, or we decided, that even with my age, I will have  a THR, I do have to accept that I will probably need a revision at some point in the future.
All this was back at the begining of August, he set my date there and then for September 21st, as he had 2 weeks holiday, and 2 weeks teaching in Australia (good job if you can get it!!)
And now we are here, I am in pain most of the time, I am lucky if I sleep for 3 hours a night, I am not fulfilling my role in work properly, and I am so emotional, I have turned into a right wimp!!
I no longer walk the dog, I take my walking stick everywhere with me, so that I can walk slightly further.  It is really hard with a stick, you can't carry things and opent doors etc!!
Basically, the 21st of this month can't come soon enough for me.  Bring it on!!
