Well my back issue was actually sciatica ... which is a new one for me.
Last week I spent all afternoon outside on my porch because it was the first truly nice, bearable weather we'd had in a while. It is a different chair than my desk chair. One I only sit in usually long enough to smoke a cigar. But last week I decided to grab my laptop and do some #writing outside. When I got up from the chair after writing non-stop for several hours I could barely move ... and it's continued since.
