Anxiety, Tight chest

I have a severe anxiety and depression during Hepatitis C treatment. My symptoms were shortness of breath, dizziness, I could not swallow, I could not talk, I didn't want to see anyone, I was not driving and much more. I felt save only in my bedroom. Thanks god I have very supportive family and great doctor. Few month past, but we steal searching for right combination of medications. My symptoms are MUCH better, I stated to drive, my panic attack are mostly under control. But now I got new symptom-stiffness in the chest, I feel like someone put sandbag on my chest. Did anybody experience this symptom during anxiety. It's scares me, I start thinking that maybe it has nothing to do with anxiety?
