i had a patient come in for some pulling under the foot. it wasnt heel tension but pain that i assumed coming from the flexor digitorum brevis area because i could feel pressure there under my fingers.
B/ hamstring tension with more tension on the L/ side was also found with SLR close to 90 on both sides. The tension in Flexor digitorum brevis was also more on the L/ side.

I just did sural nerve release for a few minutes and the hamstrings released to above 90 degrees and the tension in the flexor digitorum brevis released as well.

I have been using the sural nerve release in all hamstring tension cases and it works great.

I am pretty sure I am manipulating some other nerve pathway leading down to the area of FDBrevis

Question: Why would the flexor digitorum brevis release from above? What pathway leads to this? I still have much confusion on pathways leading to the bottom of the foot. Is there a reference material you recommend for learning pathways to the foot?
