Corn or verruca?

[Mantog]

Hey guys, so on the heel of my foot there was a pattch of dead skin that hurt when I stepped on it, so I got carnation corn capz and used them.and have feel filing down the dead skin after using all of them - and I cut some of the dead skin off today and the picture is the result.

I have a verruca on mt other foot which is slowly being dealf with due to salatac gel, but I just wanna see if anyone has any suggestions? I dont wanna go to the GP if its nothing to worry about, but I do wanna get it sorted soon as. It doesnt hurt as much when I walk now, so Im assuming the plug in the middle leads to healthy/non-corn skin and I just need to wait for the dead skin to shed?

Thanks for any help
