Sorry you’re going through this!
I’ve had 2 surgeries in June & July for mine & had a small cavity open after a wound infection & after starting on chemo, so had to deal with delayed healing. I’ve bought myself a body pillow (Kmart) for side sleeping on my good side without putting too much pressure on anything else. I also have a boomerang pillow plus a normal pillow on top under my head. Then I have my little underarm cushion from my McGrath Nurse to support the wound.
Previously I only ever used one pillow, but here I am & it’s helping me sleep.
I did consider buying a bed wedge from a medical supplies place, but didn’t end up doing that. I’ve also heard of people sleeping in a comfy recliner.
Whatever gets you the most sleep. My wound is so close to being healed now. Hoping for a good outcome with your second surgery. Big hugs to you xo
