Sorry for late reply and inconvenience.
Thanks for all these additional information.
I understand your concern.
Well as you describe,possible causes may include
Peroneal Tendonitis is caused by inflammation where the peroneus brevis tendon attaches into the base of the 5th metatarsal.
Dorsal compression syndrome
You can try some self care measures like
Use high quality arch supports and supporting shoes.
Ice your foot for 10 minutes 3 times each day.
Also take OTC Motrin.
Do gentle massage with muscle relaxant ointment on affected area.
And see a podiatrist for further evaluation and management.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
