Pf bump?

I'm about 3 years into pf both feet, doing much better, still have some slight discomfort here and there, (pushing shopping carts always gets me..)but Im back to easy running. So, I'm noticing lately that any of my footwear that has arch support starts to cause an ache. Running my fingers across the plantar tendon I notice a small bump just in front of the heels. Of course I'll mention this to my sports pod on next follow up, but I thought I'd throw it out there to see if any of you notice this. I'm guessing the arch supports press on this bump causing pressure and discomfort. I can go in flat shoes longer these days but it's a trade off, if I stand still for extended time in a shoe with no arch support,I'll get the ache. I did notice a softer insert helped. I may switch over to the lynco from my sole brand. But even with the stock sock liner in my glycerins I'm noticing this bump area getting sore..maybe time to dremel out the insoles to relieve this area..kidding..almost. Anyone else have the pf bump?
