Can bruxism cause shoulders pain and jaws pain also both sides?neck head mri norml.chest angio ct normal no cardiac issues.have infection under tooth

Yes: Bruxism can cause too much stress on the temporomandibular joints(hinges of the jaws)and is a cause of chronic jaw pains. The same type of tension and stress on the neck and shoulder muscles can do the same.

Your symptoms: Bruxism can radiate and cause other adjacent areas and muscles to experience pain. I assume and hope you are also being treated for the tooth infection. Your symptoms require a one on one medical and dental history as well as a clinical exam. Please do not rely on internet diagnosis and advice.
