@Miss Muffet, I'm sure the spasms were from doing too much yesterday and side sleeping. My surgical leg just doesn't tolerate it well yet. My problem with back sleeping is that I have obstructive sleep apnea while sleeping on my back (not when on my side), so back sleeping results in many (upwards of 60) awakenings and unconscious arousals each night, most frequently during REM sleep, and horrible dry mouth, resulting in totally non-refreshing sleep.
I tried using a CPAP machine last June so that when I was recovering from surgery I could get good sleep, instead of like after my THR when sleep was horrible, but started wheezing the morning after the first time I tried it. I kept going for two weeks, and the wheezing got worse and worse until I had to stop using the machine. It took me 6 weeks to get over the damage to my lungs, had to have steroid pack and start using ADVAIR every day (which I still must use), and I never really got back to the same lung health I had before CPAP. So I am reluctant to try it again while I am still weakened and debilitated after the surgery. I have a hospital bed, and for back sleeping I am reclined, and with my legs up, but I still have the apneas and wake often and have the dry mouth. Plus, it is very hard to be in the same position all night long. Can't really do it, and must wake up, just to jiggle my body around a bit so I don't get pressure sores!
That's why I'm really looking forward to successful, restful side-sleeping again.
I've decided to cancel the 6 more PT appointments I had scheduled through December. It is just too dangerous for me to even get to my car in the unattached garage. I'm cancelling another doctor's appointment, too. I am just going to stay home and do things here, safely, until I am more comfortable with conditions outside, or until they improve. When I go places with my sister and husband, they hover around, carry any bags, pull the car out closer, put my crutches in the trunk when I get to the door, and shake the calcium chloride over the ice in the places where I need to walk. I just can't manage on my own with all of this ice and snow on crutches, and with the sub-freezing temperatures. It is going to be -15 degrees F one day and below zero F for several days in a row this week.
