My knee hurts (details inside) - is it worth going to the doctor?

I’ve recently started training to run. I know this is why my knee hurts. (I went to the specialty store and got fitted for the right shoes, have a very experienced runner working with me, etc. so I’m not going into this blindly and just asking for trouble.)

At first the pain would subside within a day or two. (Going down stairs is the worst!) This time I am still feeling it from Saturday (5 days ago) but felt about 85% better this morning. So, stupidly, I went walking this morning and I’m almost to the point of tears.

I kept hearing “this is normal, you’re going to hurt at first” but this feels a bit over the top.

This is a two week issue, not a long-term or ongoing problem. I feel like the doctor will say ice it, elevate it, take ibuprofen and don’t run until it stops hurting. All things I already know. Is there any other point in seeing him?
