I have had problems with my joints in the past, but I never noticed any difference on glucosamine or any combination. What helped me was Alleve (Naproxin), ice, rest if its serious, and limited loaded movement, abiding by the "statute of fitness limitations" by Mell Siff (which I learned from Bill Hartman)
Remember the statute of fitness limitations as you return to normal and rehab activities. To stay pain-free:
Limited intensity or load
Limited duration (of a movement or set)
Limited volume (of an exercise or session)
Limited density (work to rest ratio)
Limited acceleration/deceleration
Limited power
Limited rate of force development
Limited velocity
Limited range of motion
Limited complexity (i.e., split squat to lunge to multiple angle lunge)
Be cautious with any wide grip or pushing activities (especially the dips due to the shoulder extension and potential anterior instability). You may find them aggrevating. Anything snatch-grip (BB complex) may also bother you.
