Neck pain/ headache from bench press?

I strained a muscle in my neck 2 weeks ago while squatting. Think I was trying too hard to keep my head up so I didn't lean forward. I've had a headache in the back of my head / base of my skull ever since. I think Sunday was the first day that I didn't have to take an Aleve to dull the pain. Feeling much better today and I think I'm ready to lift again.

Carefully stretch it? Idk

Same exact thing happened to me when I was a little younger. It was frightening.
I immediately stopped working out that day. Took a couple days off from the gym and it happened again 2 days later as soon as I tried to lift weights.

Took 3 weeks off and it hasn’t happened since.

In hindsight, I probably should have gone to the Dr

It's strengthening and being in the correct positions.

Do you lift for strength or size? Size doesn't mean weak in this scenario.

If strength, really look into proper technique with the shoulders pinched together and most of the pressure is on your back and lats. I pick up my head a tiny bit but nothing like Mark Bell or people similar. The issue with this technique is that it doesn't hot the chest as much.

For size, create less of an arch and flare your elbows a little more. Don't worry about touching so much since you aren't competing. If you aren't worried about touching, you aren't worried about your head coming off to see if it did.
