Peculiar pain referral

Client reported pain the in the arch of the foot. To relieve it I compressed the fibularis muscles one section at a time while passively flexing the first metatarsal. He reported referred pain in his Achilles tendon which makes sense.

What’s strange is the rest of the referral pattern. He also reported referral pain in the lateral patella at the distal vastus lateralis. Then there’s the sub occipital pain. All on the same side.

Anybody here knows what they’re doing concerning pain patterns? I’d like to know more about this experience. For context, he is a frequent runner.
