IPadGrandma hello. In answer to your question no I didn’t have crunching or rumbles but then I am a bit deaf, only joking but was certainly in a lot if pain, as you are.
You can rent wheelchairs from Red Cross and Age Uk might be worth a look. I got my walker from a charity shop, and still use it to get in and out of the shower. It does have wheels in front but I feel quite safe.
Hope I don’t need built up shoes Humpty.
Travels once you have had the operation you will wonder why you worried, easy to say as I was worried too, but looking back it was almost a walk in the park.
Have you checked Red Cross who used to provide a 6 week post op home visit, service, think Susie had it.
