I suffered from PF many years ago and was friends with a physical therapist. She gave me all of the usual recommendations for treating it and nothing worked for more than a day or two. At some point, I ran across a website for a PT clinic that recommended the ROTATIONAL HAMSTRING STRETCH. I began doing a set of 25 on each leg 3x a day. After a couple of weeks, the pain was almost gone. I found I could gradually begin reducing the number of times per day and then the number of times per week that I did the stretches, until I just needed them when I noticed a slight telltale pain. After a few months, I didn't really need them at all, but had discovered that they kept the little annoying back and neck pains away as well. Here is a link to a description of that stretch and others, but really, I think the hamstring stretch on its own will do it if you want to keep things simple. This was a miracle cure for me! http://accurateclinic.com/wp-content/uploads/2016/01/Accurate-Clinic-Plantar-Fasciitis-Exercises-10-4-2011.pdf Edit for more info: https://runnersconnect.net/hamstrings-plantar-fascia-injuries/ TLDR: "In fact, after controlling for other variables, like BMI and calf tightness, the study demonstrated that having tight hamstrings made you nearly nine times as likely to suffer from plantar fasciitis."
