I'm sorry that you are so stressed about your upcoming surgery.
You know, this is a voluntary operation and you can decide to just not go through with it. Poof! That anxiety is gone and you won't cry over it any more, even though your present anxiety is temporary. But you probably will have months or years of anxiety and tears as your not-so-functional original hip causes you pain, frustration, and loss of quality of life. You can decide which will serve you better over the course of your life.
Your surgeon and the care team will make sure you have effective pain relief all through recovery. My experience was a pain level of about 7 immediately after surgery - snd that was the incision stinging only, nothing to do with the new hip implant. The implant and residual pain level was about a 3 at the worst, and easily controlled with prescribed meds. I still have 15 of the 20 tablets prescribed in the cupboard, a year later.
I was like you, wanting to know what was going on during surgery. But that was only because I'm curious and nosey. It's not like if you are awake and aware that you have any control over the situation anyway, and no one is going to ask for your opinions about what's going on. Sometimes ignorance is bliss. Remember that the surgical team does hip replacements every day and it's routine for them, another day at the office.
I've read my intra-operative notes, and the attention I received, and every patient receives, is phenominal. Someone in that OR is very busy making sure your body is doing well, that you're getting everything you need for a great outcome. Even before the surgery, and in PACU, someone is always checking. In my experience, all my concerns were addressed quickly and in a professional manner. The team was fantastic.
I suggest that if you have particular concerns, for instance pain control, talk to your surgeon or his office patient advocate person about it. They can be a great help when you're worried about meds, home care, and anything to do with surgery and recovery.
On the meantime, stay busy. Prepare your little recovery nest, get ahead on household chores like laundry, cleaning, grocery shopping, and that sort of thing. Don't borrow trouble thinking about what ifs, only imagine how great losing that grinding hip pain is going to be. Order and practice with your recovery aids so that you'll be familiar with using them. Read threads here on BoneSmart so you can get realistic perspectives and experiences...and know that good outcomes far outnumber less successful ones.
Don't worry about being worried...most people feel anxiety pre op. Take some time to breath and mindfully relax and think about a great positive outcome.
Best wishes for you.
