NC welcome.
You've been struggling for a very long time, the HR will be a huge relief. The grinding bone pain is close to being gone so congrats in advance. Sorry the road since the labrum work has been tough, like Ross mentions above, my doc said fixing that really wasn't worth it given the low probability for it resolving much.
Side sleeping wasn't possible for me for a few weeks, apply fresh ice packs before bed and put a pillow under your knees when on your back. Recliner as Boomer suggests work for many. Once you can entertain side sleep, use a pillow either to rest your upper leg (when on your side) on the pillow, slightly in front of the bottom leg, to keep your legs parallel or some also put the pillow between the knees to keep them parallel. This prevents pressure on your operated hip from the leg being out of parallel/torqued etc. For me at maybe 4 weeks I did not need the pillow.
As far as your recovery, stay iced, follow the restrictions and do the post op exercises or PT, stay ahead of the pain when necessary, and you'll get through it with flying colors. The recovery is nothing to sneeze at for sure, but the benefits you will soon see will make it worth it.
