What happened to my heel? It's tingling

I overtrained. A week later, my heel is still tingly and uncomfortable. What's going on? My left heel has felt tingly and kind of weird for about a week now. It's not really painful, just uncomfortable and annoying. If I'm focusing on something else it's generally ignorable, but when walking I'm leading with my toes to avoid putting pressure on it as it's uncomfortable to land on the heel regardless of the shoes I'm wearing.

Me: Mid-20s, moderately high blood pressure, low body weight, been running for about a year, slight pronator.

Timeline: Two weeks ago on Wednesday I went for a 15-mile run. I'd previously run a few half-marathons and I generally run at least 10 miles / week. I felt pretty much fine afterwards.

I was thinking I was pretty hot shit at that point, so the following Monday I went for a 10-mile run. I don't exactly remember when it started, but sometime after that is when the tingling began. Nothing remarkable happened on this run, but I did feel a bit dehydrated at the end (it was much warmer than the previous run).

Friday night I felt like I had had enough of this and went for my usual ~6 K run at a personal-best pace. Nothing changed for better or worse after it.

Speculative diagnoses I've looked at:
* Plantar fasciitis: It's not really painful, just uncomfortable. No change in symptoms in the morning. Walking or running makes it feel slightly worse.
* Sciatica: The sensation is very localized and there's no numbness.
