@oregonjan If you decide to go with a shoe lift, here is what I was counseled (I had a 1/2" difference, reduced to 3/8" after surgery). The lift should only correct 1/2 of the length differential. The lift should be worn gradually, beginning with 1/2 hour, then 1 hour, etc over several weeks until your body adjusts to it - it took your body years to adjust to the length difference, so going the other way takes a long time too. Then, if there is still an issue, a little more lift can be added.
Also, even though a walker seems like "going backward" maybe it is better than not being able to go at all? I was thinking of the forearm or upright type to avoid additional stress on your hand and wrist (I was 61 at my last hip revision, and couldn't use a walker because of my wrists - forearm crutches were what I could manage.)
Just thinking out loud. Good luck.
