I can only tell you MY experience. At age 30 I got my first glimpses of what was to come. Stiffness, occasional pain, etc. would creep in randomly. I began taking Osteo-Biflex and other glucosimine products as Osteoarthritis runs in both sides of my family.
Fast forward 30 years...
My husband and I had my 99 year old mom here at our home for two years. Lots of work, even MORE STRESS. Both my husband and I found marked physical issues starting to rear their ugly heads! Mine was my osteoarthritis. His was the pheripheral neuropathy associated with his diabetes.
Because pretty much ALL of our attention and time needed to be focused on my mom, we put our aches and pains on the back burner.
That was four years ago, and Mom has since passed away...just 25 days shy if her 101st birthday!
Comparing my X-RAYS of my knees from FOUR YEARS AGO to those of just a couple months ago, the damage was UNBELIEVABLE!
FOUR years ago my knees still had cartilage. They were alligned. They had bone spurs, but the damage hadn't yet gotten TOO awful . Insurance would only pay for PT and cortisone. They refused to pay for the injections of the rooster combs that is SUPPOSED to boost levels of cartilage.
My cortisone shot helped only for four DAYS. I was very discouraged. Then we had my mom here, so things got put on hold. That was 2011.
In May of this year (2015) SEVERE PAIN took me back to my doctor.
New X-RAYS showed BONE-ON-BONE, no cartilage, but MOST DISTURBING was seeing the BOWUNG of my legs AND me literally walking on this tilted one inch piece of bone-on-bone of my inner knees! (By the way, I had WORN OFF all my bone spurs by WALKING!!)
DOC said I had two choices...do nothing OR repkce BOTH KNEES!
After seeing those HIDEOUS X-RAYS, I KBEW I had no choice IF I didn't want to spend the rest of my life in a scooter or wheelchair.
I'm 64. Longevity runs in my family. Spending my next 40 YEARS in a wheelchair didn't sound good to me,csi I booked my first surgery THAT DAY before I left his office!
My second knee is scheduled for October of this year.
I hope this helps!
I wish you much success and NO PAIN!
