Skin pain on back/side of neck

Hello all - I just started dealing with this problem yesterday but it’s concerning me.

I have pain on the back of my neck, near the base of my hairline, and it travels down a little. At first, it really felt like a rash. It’s not itchy at all though, and there’s no sign of a rash. No bumps, no nothing. But touching the area hurts... I recently wore a necklace with a different chain and I thought that could be the problem so I took it off, but it didn’t relieve anything. When I press on it, it hurts, making me think it’s muscle and not skin, but it really feels like it’s on my skin even though there’s nothing to show.

And the pain isn’t like soreness, like whiplash or I slept on my neck wrong. It’s like I can move my head freely but touching that one particular area gives off a slight “burning” pin pricks feeling.

I’m not diagnosed with anything else, so I’m not sure where this is stemming from or what’s causing it. I’m open to any suggestions or ideas. If it continues to persist, I will be going to the doctor. Thank you for reading!
