Lower leg pain

[sorryiasked]

My lower leg hurts as if I've got a bruise, only there's no discoloration or swelling, and I don't remember knocking it on anything.
It's on the front/outside of my leg, approx half way between ankle and knee but not over my shin bone.
No rash or heat/burning. Not exercise related as the only thing I've done recently is very little walking
Any suggestions? It's been like it 3 days now and I don't feel I can ring nhs and say my leg hurts with no other symptoms!

Bumping in case anyone has a suggestion as it still hurts!

Hey love if you massage your muscle does it feel sore as in it’s been over worked? I ask as I had similar thing for years saw loads of professionals all had no idea I ended up going to a foot specialist and learning that my alignment is all off and I needed insoles! Fast forward a few months later pain has gone and I no longer need thé Insoles.

@Theidealcat thanks for replying. No, doesn't feel muscular at all. It's very strange it really hurts if I run my hand down my leg, but hardly at all if I run my hand upwards. No mark/rash etc but I think it's slightly numb in one area.
