Oh, ouch! Maybe a hot bath before bedtime will help some. And make your ibruprofen a double dose. You can safely double dose for a few days and the extra really makes a difference.I was raking up more leaves, and cutting back some perennials, and when I stood up, I must have twisted my lower back, because OUCH.
I've taken an ibuprofen, and been applying an ice pack, and it sometimes feels better, and other times not so much. I expect tomorrow morning will be bad getting out of bed, but hopefully it won't hurt as long as it did 2 years ago. Guess no power walks for a bit though.
