Knee Pain when running, how to reduce, reverse and prevent Knee Pain

Several years ago when I was much younger, say in my early twenties, I suffered from knee pain anytime I ran.  To treat this knee pain I used the most current methods known to modern medicine, Ibuprofen.
Upon waking and prior to running I would take an 800mg table of Ibuprofen.  Now this certainly worked, I was able to run without pain, and I was young enough that my stomach and liver and kidneys could handle the damage I was inflicting upon myself with chronic medication.  I also did not know that NSAIDs such s Ibuprofen and Acetaminophen prevent the body from healing and repairing tissue.
In fact I have since leaned that recent studies have implicated Ibuprofen specifically in preventing the body from repairing soft tissue.  This means that when I took Ibuprofen after an ankle sprain, my body had a more difficult time in repairing that ankle sprain that then lead to a higher chance of spraining that ankle again.  It also meant that the damage in my knee that was causing my knee pain also never could fully heal.

So no that I am older, but yet leaner, and faster how do I take care of my knee pain.  Well I changed the way I run entirely.  I no longer run in heavy stability and motion control shoes, instead I run in light shoes with very little heel and minimal padding and cushion.  I have learned how to run on the front of my foot striking on the balls of my feet.  This uses the natural arch in my food like the leaf springs on a truck axle and engages my calf muscles eccentrically like shock absorbers.  By running in this way I also have change the angle of my center of gravity over my point of balance.  In making this simple change I have improved the bio-mechanics of my running motion and I no longer suffer knee pain.  I now run faster, greater distance, all with no knee pain and none of the horrible but silent side effects of chronic NSAID usage.

This is not something that happened overnight.  I spent a few weeks performing drills and conducting short runs to build up strength in my calves and soft tissues.  But in less than a month I was able to run without ever letting my heels slam into the ground and thus absorbing all the shock and impact below my knees.  Running pain free is great.  I learned how to do it from watching video demonstrations of Dr. Romanov and his Pose Method.
