Brian,
Although I am very new to the forum you've given me some very helpful insights and suggestions to the PN struggles and I want to add my sincere best wishes for the best possible outcome for your hip replacement surgery. I hope your surgery will be uneventful, w/ a speedy recovery and give you long-lasting pain relief.

My old boss had the surgery a few years back and his life has improved dramatically ever since - he's now 85 and going stronger than ever!
