Welcome to our forum! I’m glad you’ve joined us but am sorry you’ve been diagnosed with Eagle Syndrome!
The answer to your question is that trap, clavicle, & scapular pain are pretty common ES symptoms. They’re caused by irritation to the spinal accessory nerve (SAN) by the elongated styloid(s) &/or calcified stylohyoid ligament(s). Numbness in your hand or arm can be a response to severe SAN compression or irritation, but it can also point to possible Thoracic Outlet Syndrome (TOS).
If your styloid(s) is/are elongated & you have SAN symptoms & possibly others you don’t recognize that are caused by ES, then the radiologist is wrong who definitively told you that you don’t have ES. Medical people who haven’t experienced ES themselves often lack understanding of how broad the spectrum of ES symptoms is.
