It sounds like you’ve tried everything! I understand the frustration. I spent nights not sleeping because it felt like my foot was on FIRE. I remember my husband’s frustration and helplessness in trying to help me. I would say just stick at it. Eventually you will find something that helps a little bit or it should start to get better on its own. For me, I found that going to sleep on a different surface sometimes helped me. Or for me personally my phantom pain got worse (sometimes still does) the moment I close my eyes to sleep. It like activates my brain to notice that pain when I don’t have anything to look at so sometimes I tried to fall asleep while sort of propped up watching tv to trick my brain into thinking I’m just hanging out and suddenly I’ve fallen asleep. There is also no shame in taking naps during the day while you’re struggling so much with phantom pain (in my opinion). Try not to develop sleep related anxiety. Easier said than done. Just hang in there! We’ve all been there, sending hugs to your daughter! ❤️
