DanC,
I hope things get better for you, as far as the addiction to percocet, I think most back patients get hooked on one drug or another. The doctors love to give the meds out like candy. As your back gets stronger you'll depend on them less and less.
You have shown a lot of strength, This is never "easy", but you are making great strides it sounds like, for that I commend you.
I will keep you in my thoughts and prayers as well, each step can be a struggle but you can return to most of the activities you are acustomed too.
Just remember:
Get your strength back before testing the waters too much.
Exercise and stretching are very important.
Sometimes we all need a little help, don't be afraid to ask for it.
I salute you, I don't know that many that have walked where you have and made the return trip
God bless you and yours
Mike
