My lower back is fine as long as I am standing, moving around, etc. But after I ve been sitting awhile and try to get up, my back hurts so badly that it takes me a minute or two to stand up straight. I am 86 years old and unable to be on my feet for long periods of time. I try exercising my legs a couple of times a day, hoping that might help. This has been going on for a week, so would be very happy to be reassured that it will probably be okay. I ve had similar problems with my back since my 20 s occasionally, but it usually cleared up sooner. This started the day after my 17 lb, dog was given anesthesia (sp) for his teeth cleaning, and when I picked him up at the vet, he was so drowsy and unhappy that I carried him into the house when we got home.
