Hi, everyone, Thanks for your helpful answers to my previous questions. I'm now in week 9 of my first bad crash after having mild symptoms and being quite active for several years (working, bike riding, light running, lifting heavy boxes, etc.) I'm in bed (awake) about 14 hrs/day now, mostly housebound, and really dependent on others. What do people think about resting lying down vs. sitting up? I feel better lying down--more rested and less lightheaded (I'm getting tested for OI in a few weeks, hopefully). But I wonder if it's bad for my body in general or my OI to be lying down this much. Also, I'm beginning to develop pain in my upper body muscles from doing the simplest "everyday" activities that would never have caused pain before, and maybe also my sleep positions. My ME books say you shouldn't do strength work until you're doing walking exercises, and shouldn't do walking till you've got enough energy to easily do housework. I was there a few weeks ago, but have gotten a bit worse from moving house. Any ideas on whether it's OK to get up and do gentle exercises when in bed most of the time? Or whether it makes a difference that I was quite active 9 weeks ago? Thanks!
