Sorry to hear about your new difficulties Tin. Transferring someone whose mobility is failing is really hard. I've left mum in bed today as the strain on my lower back is really worrying me these days. I hope that it's just the infection and/or antibiotics causing the issues for you and that the phase will pass. I think in some ways it's easier if they are mobile OR bedbound, in mum's case she can still stand, so I feel bad leaving her in bed, but after a day of transfers to and from bed, wheelchair, commode and recliner I'm shattered and my back starts to hurt, so I really have to avoid doing this all the time. But, I feel bad leaving her in bed!
I'm finding the small incontinence sheet wrapped around mum's her left side at night time is really helping the leaking issues, but I now have mum leaning to the left in bed, and sometimes in the morning her head is at quite an angle, so from tonight there will be another pillow under her left side, hopefully this will stop her moving to the left.
I've been SO tired with it all recently, and close to giving up, but haven't yet. I think leaving her in bed some days will help ease things for me, I hope!
