No advice but sympathies. I'm 37+3 and sat downstairs since 2:30 am unable to sleep for the seventh night running. Whole body aches, baby's head is ramming Into my butt, my perineum and bum hurt like hell. My ankles look like stuffed stockings ready for Xmas and my fingers?
Well let's see about my fingers. At 7 months they started getting locked in the mornings on waking couldn't straighten them till a couple of hours. Same now. Had taken my rings off then else they'd need to be cut now. Swollen fat lumps each finger is.
I find baths help a bit with some Epsom salts in them. Can't fit myself into a bath on my own, so I plug the bath run the hot shower and put Epsom salts and lavender oil on the floor of the bath shower runs on me while the water fills up and soaks my poor feet and I get some lavender smellies. This approximation of a foot bath cum shower I have called a bower. I'm a sad person.
Sorry I have no advice on the rings. So some is sure to come by, but commiserations from a fellow swollen, fed up insomniac who's had breakfast at 4:35 am consisting of banana milkshake, (now prepare to vomit) - followed by yesterday's rice and two whole grilled aubergines with various Indian spices. Heartburn will now hit.
Can you ask someone like a DH if poss to massage feet and hands draining fluid away from tips towards the body? DH does my feet away from toes towards the thighs. Same would go for fingers I suppose. Keep them elevated,
