Don't be surprised, now that you've signed the consent for the THR, if your painful hip takes a wonderful turn for the better. But don't be duped! It's just a deceitful game on the doomed joint's part! It's likely only temporary and if it's anything like mine, will just as suddenly revert and get worse than ever.
I think it's not unusual to have doubts...Is it really that bad? Can I wait a while longer? Will it be worth it? Will I really do better afterwards?
Of course the decision for the surgery is yours alone. But I can tell you my experience is that the pain and incapacitation only got worse week by week. I gave up too much to accommodate the bad hip - fun times with my young granddaughter, road trips with my dh, my favorite outdoor hobbies, and more. I'll never get that time, or those opportunities, back.
Bu my new hip is giving me new chances to live the life I want to live. I don't regret the surgery one bit.
I wish you calm and peace as you move forward, whatever you decide. Good luck to you!
