Plantar Fasciitis (secondary to…)

I have had plantar fasciitis for several years. I’ve been service connected (prior to the plantar fasciitis) with both lumbar and cervical degenerative disc, and both knees (instability) at 10%. I believe the issues have changed my gate and a few years ago my feet began to overpronate, which is the same time i started having feet problems.  Has anyone seen trying to secondary connect the Plantar Fasciitis to the back and/or knee injuries. I realize a doctor would have to agree and provide evidence, just seeing what you all have seen. Thanks.
