Are you telling my story? In 2008, I had my left hip replaced and woke up to gross sciatic pain with a dropped foot. I did get my foot back after intensive water therapy for 1 /1 and one half years. My condition came from back DDD and every other diagnosis you can think of. The problem is I don't make the decision - the pain does when you reach the point of despair. My right hip was done in 2019, and guess what no dropped foot, but the femoral nerve was damaged and felt like fire crackers in my leg. I walk fine, but getting up and down was horrific.
It gradually abated 18 months later. Wish you good luck on this
journey. When I finally could get into bed I'd put on YouTube and turn on meditions it helped greatly.
