My legs are definitely wibbly wobbly at the moment. I am putting the weakness down to the heat not progression.
Falling, even in the house, is a demoralising experience. I just want to sit and cry when it happens to me even if I haven’t actually hurt myself. About 2 years ago I accepted an indoor electric wheelchair but my plan was to put it in the corner with a nice throw over it! Actually it turned into a boon. I relished the ability to scoot from room to room with very little effort. Suddenly I could get food, a cardigan, my specks that I had left in the bedroom. My daughter said she felt much happier knowing I was safe and I felt 100 times more independent.
My GP referred me to wheelchair services and I got an indoor electric chair because I was falling and I didn’t have the strength to self propel. (I’ve got an indoor/outdoor chair now but at the time got only an indoor one) I don’t know if a chair would help your husband but be prepared for some resistance. I didn’t want a chair it was concussion that forced it on me!!!
