What the fuck is wrong with me?

For a year now my neck and upper back has been feeling tight on and off. When it’s tight I feel like my neck is going to snap (makes me slightly dizzy).
I also feel pressure or mild pain in my temples (is this a tension headache?). My back feels so tight when I take off my shirt it’s uncomfortable to move.

Showering helps alleviate the symptoms for a while but it comes back. Symptoms are not present in the morning.

Head MRI came out clean. Waiting for the others but I have a feeling they’ll find something chronic.
Does this sound like a neck or back issue?
