Just thought I'd post an update.....the good news is, the ART worked.  After 6 session, I went out for a run-walk, and the pain under my knee was gone.  The bad news is...a new pain appeared on the upper outside of my knee.  I assumed it was because I hadnt run in months and had to get used to it again.  Over the next couple of weeks, I continued to try, but the pain got worse, and sometimes was on the upper inside of the knee.  Then...I noticed I had minor pain when walking.  That was going in the wrong direction!

The chiropractor said the location of this pain was not in a place he could do something about, and he referred me to physical therapy.  What the therapist thinks is that my knee is not tracking correctly.  I have flat feet, and my custom orthotics are about 12 years old, and her orthotic person looked at my orthotics and my feet and said it didnt look like they were providing the right kind of support/alignment help.

So....I now have exercises to do at home in addition to my twice/week PT sessions, am wearing kinesio tape and will be measured for new orthotics in a few days.  It will then take about 3 weeks to get them back.

In the meantime, the therapist said not to try to run....which is hard, because actually, my knee is feeling good right now, after two sessions.  But I dont want to mess this up, so I will be patient.  I'm hoping I can run pain-free by Christmas.

I'd be interested in hearing from anyone else with flat feet.  This explanation makes sense to me, I just hope it can be "fixed." :-)
