I have a question regarding the energy drain people post about. Ever since coming out of surgery, I felt pretty good, pretty alert, able to throw myself into anything you can do lying flat on your back with your knee propped up. In other words, reading, watching TV, carrying out complicated telephone conversations. The travels over the past two days made my leg feel stiff and sore, but didn't wear me out at all energy wise. So I'm wondering, is that the difference between general and spinal? I had the spinal, and have never felt any sort of brain fog. Now when I take the pain pills, I eventually feel a wash of sleepiness and drowse off. But that's different than overall not feeling alert and energetic. After the shower today, I felt fine, energy wise. And since I'm a very heavy 60-year-old, I don't have any pretensions to having to come into this with the best of health. So I Suspect it must have to do with the anesthetic. Either that or the kind of medications the doctors put us on afterwards. I do Norco's, and that's the strongest drug I've been given. Anyway, it's interesting. But the discomfort, swelling and tightness were inevitable.
