My Dad suffers from PNR and literally could not get out of the chair. He began taking MSM (organic sulfur crystals) 1 tsp of the crystals in a little liquid TWICE a day. Bought them on Amazon.
He couldn't get out of his chair...joints hurt him that bad but he is now regularly walking down to the chicken coop. The sulfur worked pretty quick...I think he really felt the results in his joints within a week. He added the other thing later so they at this point may be working in conjunction.
