Is a sore/stiff shoulder worth going to the doctors over?

Does anyone have experience of a sore shoulder just healing over time?

I feel like I’ve slightly pulled or mis-lodged something in one of my shoulders and it’s been sore and stiff for a few days. I can also feel a small bone protuberance in that shoulder that isn’t in the other.

I’m in the UK so doctors fees aren’t an issue but I’m not sure if surgeries are opening up to anything that’s not serious because of covid.
