I had a left THR due to osteoarthritis about 15 years ago. I had to wait about 3 months before I could drive and then returned to work as a teacher. I was tired but not in pain anymore.
I recommend lots of walking and rest in between and strengthening exercises using bands (which they give you). Buy a litter pickup grabber for a fiver, and do obey the rules about bending etc to begin with.
I was diagnosed and given a date of about a year, but luckily a cancellation came in about 5 months later. Ask them for the cancellation appointment as they don’t always offer it.
For now, get a TENS machine for during the day, it really helped and it is only about £30. I also used a long pregnancy pillow from Amazon to help sleep at night. A blowup cushion with a hole in the middle is comfy too, when you can’t find the spot. Also they will lend you a zimmer frame and toilet frame from physio before your op, hang a bag from the frame to carry your book, crisps, water bottle etc.
Your sleep will be broken but they do help.
I had a spinal anaesthetic for the op, as I felt it helped me mobilise faster the next day. But it’s a personal choice.
Don’t go too fast in recovery and don’t feel ashamed to go downstairs on your bum, do what works for you.
Good luck
