First I want to clarify that I'm not a medical professional of any kind, and my advice is based on alot of experience. I've dealt particularly with shoulders and knees. Unfortunately, I've never encountered conective tissue problems with feet. Usually, pain in the feet are a result of small fractures in the metatarsuls, from what I understand. I did find this info. for you though, (link), hopefully it helps, it sounds like what your dealing with.
