Popping, tightness, and sore

I am trying to find something to relieve my tight sholders, back, and neck.  It is alittle annoying alreadly having these symptoms at 22 yrs old.  I am active and I work 60+ hours a week on fighter jets climbing on ladders and contantly moving.  I've tried stretching, exercises, and vitamins.  My joints are contantly popping too.  I dont know if it has anything to do with the tightness or if it is normal.  My joints dont hurt when they pop.  Is there anything I can do?  Is the stiffness and being sore just a result from being very physically active?

Yes, The stiffness and being sore just a result from being very physically active.perhaps your posture while you are working lead to neck trouble,then conductable pain go to shoulder ,compensative pain in back.
