Improving 10k with regular training

[MMS]

Hi,

I went out for an easy 30min but felt something on my right heel, like someone was sticking a needle there. It happened after 17min, right after a left turn that is slightly inclined. It felt once, I kept going then felt it over two times, when I decided to stop. I walked for 3-5minutes and ran again for 12-13 minutes but didn’t feel anything at all this time.

It’s the first time I feel something like this. Of course, the first thing that crossed my mind was that I could be injured again. I’m not too much worried right now (and please let me know if I have any reasons to be) because I don’t have any of the classic symptoms of the achilles tendonitis (felt when injured): that pain especially at the first step in the morning, or rising after long periods of rest, or even any tenderness in the area (the latter never happened).

I did my usual stretching exercises and started icing the area/take anti inflammatory.

Any ideas of what it should be?

Ps: trying to keep a positive mind right now.
