Back home after taking Mother for her quarterly checkup. My troublesome knee & back came good with the aid of painkillers & anti-inflammatories, both oral & topical. Slighty sore back, a bit more than is the normal state of affairs.
Oddly, it wasn't until my sciatica & lumbar stenosis were diagnosed two years ago, that I realised I have a small degree of permanent pain in the lumbar region.
