Trapezius strain?

Last week I had horrible body mechanics. Shoulder rounded forward, upper thoracic rounded forward, neck hanging. This last week I can barely move my neck. My traps are solid as a rock. I feel trigger points all in my traps. I will be having my 3rd massage in one week tomorrow. The massage helps and then I wake up again with widespread pain and even more adhesions than before. I’ve gone to the chiropractor (which is making it worse) , taken prescription NSAIDs and muscle relaxers. Have any of you had a trap strain before bc I’m thinking that’s what this is. Limited rom in my neck and my upper back feels pain spreading all throughout my shoulder blades.

Edit: also going to cedar point for 3 days this weekend and I’m so nervous I will hurt myself more. But $500 as gone towards this trip and it’s non refundable 😭
