wow
lot of guys with back issues here
Lots of good advice too.
I have had pinched nerves and sciatic nerve issues.
Mostly time and stretching helps.
Takes up to a month to heal after a flare up typically,
with the sciatic a few months.
Being a carpenter does not help.
If your stomach muscles are not strong, they will have a hard time supporting your back, so strengthening them should help further injury.
Thing is , its hard to strengthen when your hurting.
I found super feet boot inserts make a big diff for me with decent arch support(got high arches)
Doing rep leg lifts to a 90degree and hold helps too in the morning.
Not sleeping on the couch helps too.
For kayaking I bought a small thermarest cushion
keep it half under my seat, half at my lower back.
made a big diff for those 12 hour days...
