I woke up last night with a pain at the base of my neck slightly to the right side off center. Hurt bad enough that I took an extra xanax to get back to sleep. All yesterday it hurt. It’s a constant pain. But it doesn’t increase with movement so it not muscular. The only thing that increases the pain is when straining. Like doing the valsava maneuve. Think trying to force a poop. Other than that, nothing really increases it. Nothing alleviates it as well. I can’t get the thought out of my head that it’s an arterial tear or something of that nature and it’s just waiting to fully tear.
