A word to the wise - if you have a slouchy sofa that doesn't offer comfortable support, ditch it. My ex has such a sofa and it finally got him; sciatica hit a few days ago and today I spent the afternoon transporting him from his doctor to the imaging lab for x-rays then to the pharmacy for the prescriptions. I've sent a note to the kids that we need to pitch in for a good recliner for him for his xmas gift. Today I took the walker that was provided with my first knee replacement surgery (and not used much then or with the second surgery). He has it at the house, along with two prescriptions to reduce the inflammation. We also stopped to pick up dinner for him, and I got one that was full of calories because he is underweight. (Macaroni and cheese is comfort food - and when you get it from a French restaurant it has sharp cheese, basil, and extra chicken with a croissant on the side.)
