I have had this from running and can relate to your suffering. The heel and arch inserts made it worse for me. Try going w out them for a few weeks and stretch!!! PF is a culprit of tightness in your Achilles' tendon. Google
how to stretch this tendon. I push on a wall w a strait leg the slightly bend at your knee. The stretch will run down from your calf to the tendon. As frequent and often as possible while crushing Advil. Ibuprofen. Of course talk to you dr.
