Could A Stiff, Tight Feeling In My Neck And Head Pressure For The Past Few Days Be A Strained Muscle?

I have had a stiff/ tight feeling in the back of my neck since Friday. It doesn’t hurt and i am able to move it all around without issues. It does feel extra tight when i put my chin to my chest but i am able to do it. My head has also felt pressure feeling / tight as well. But no pain in my headorpounding. I have been feeling tired as well. But no fever and no vomiting or anything. Should I be concerned about meningitis or does this sound more like a pulled/ strained muscle ?
