I'm the same way my body is so sore i feel like I pulled a muscle the pain just doesnt go away its mainly on my shoulders and chest mainly on the left side but it's more when I move certain ways or intentionally try to see if the pain is there. It causes my anxiety to be worse.
Yes I have had many tests ran..everything fine
Doc thinks its anxiety
Have you been checked by a doctor? If not I would at least go get a check up.
