Neck pain and general sick feeling

(21F) Around 5 days ago, I noticed that my neck felt sore. The soreness is on each side of my neck towards the back, kind of behind my ears (but on my neck).

I can still completely turn my head/ move my neck, its just very sore when I move it around and even when I just touch the outside of those areas with my hand.

I've also had a headache which started happening maybe three days ago, it isn't extreme and id rate the pain a 3/10 with it being more annoying than anything.. the headache isnt completely consistent, it hits me at random times especially if im sitting and i stand up, but it does keep coming back.

Additionally I feel very faintly feverish, but its just the feeling of chills every once in a while and also isnt consistent. I drank a bit with some friends last night and woke up at 4 am feeling like I definitely had a fever, but I drank some water and woke back up in the morning back to normal.

I know it might really be nothing, but I have severe hypochondriac issues so im convincing myself I have meningitis or something extreme like that and getting really scared. Does this seem like something I should be worried about or could it just be sore muscles from sleeping on my neck wrong and I have a cold or something?
