I’m sorry you are struggling
@MagsE66 . I fear that you may be sick of hearing the same thing, but it’s still true, that you are at an early stage of your recovery, and you will feel better, given time.
Lack of sleep is normal at this stage, and makes everything feel so much worse.
I kept a detailed daily diary of my first THR recovery, and I have been looking through it to see where I was after 5 weeks. I see that, like you, I was feeling discouraged. I then compared where I was after 36 days with the situation at 6, 16 and 26 days, and then I could really see progress. ( This was Layla’s suggestion, to look at progress in weekly jumps. Since I was slower than average, I decided to use 10 day jumps). That cheered me up a lot. But then I tried a bit too hard with exercises. The exercises seemed fine at the time, but the next night I was awake with pain, and had to resort to taking codeine. I had been off all painkillers for a few days, so clearly I was feeling like I was going backwards. But soon after that, I was improving again.
So I think I was very much in the same position as you at the same time. And, eventually, my hip was perfect. Which is why I keep saying, hang in there! It will get better!
I note that you have tried gentle exercises and no exercises. But are you taking into account that you have transitioned to using one crutch? And maybe trying a bit with no crutches? Any change will be giving your leg more work to do, and may trigger pain. Maybe try going back to two crutches for a few days. Whatever you can do to rest your poor sore leg.
I do so hope that you will feel better soon.
