Can anyone suggest an expert bike fitter? Someone who has background knowledge of physical therapy or kinesiology.

I bought my first road bike just a few years ago, had the bike fit where they focused on knee angle. I didn't have any problems with pain, maybe because of all traffic lights I was moving all the time. 

Life changes and now I do rides indoors on my smart trainer 2x/week sometimes 3. I had inner knee pain/discomfort with my left knee, kept going and it got worse then my right knee was sore. I stopped, rested, ice etc, etc I took off my SPD and put on flat pedals. I was hit n miss riding, mostly missing. With Primavera coming I started riding indoors again regularly and inner left knee pain is back. So, clipped or flats I'm having the same problem and need this fixed asap. If you know of a professional bike fitter (not a company trained one) please let me know.

Thanks,
