Please tell your H I'm so sorry about his sciatica. 4 years ago started having problems with mine, so I know how much it sucks. I basically couldn't walk, pain down my whole leg, prescription painkillers and physical therapy, the whole deal. Then of course it lasts for a while, and you start thinking it'll never go away, and you feel like everyone else thinks you're crazy and overreacting - chronic pain is tough. Mine's a lot better, but it still hurts sometimes (I actually want to start being more proactive about it, going to the chiropractor and trying acupuncture to see if that helps).
Anyway, just wanted to commiserate and wish you both the best.
