going up a flight of stairs was painful for him
My husband was diagnosed with arthritis in the knees a few years ago.  He decided to try Flexcin to see if it would help relieve the pain in his knees.  It did and today his knees feel well enough to do 4 mile hikes with the dog multiple times per week.  Before Flexcin, going up a flight of stairs was painful for him.
