Symptoms changing.. is it anxiety or something else?

Mental health

I’m 24 and I’ve been dealing with sudden extreme anxiety for about 2-3 months now and have struggled with so many different symptoms, which has caused awful health anxiety. My worst symptom has been my chest pain. I’ve had chest x-rays, EKGs, and stress test and everything looks normal. I have been seeing a therapist and working on trusting that this pain is just anxiety and will go away if I truly believe that. Yesterday, I noticed myself really working through my chest pain and not giving it as much attention and it seemed to really go away. But last night I started to suddenly get this pain in my right shoulder, neck, jaw, and head. I’ve also felt a cold sensation in my right side head since last night. Could this just be my anxiety symptoms changing to something new? Has anyone ever experienced these feelings?
