Chest Tightness Conversion Disorder?

For the last nine months I have experienced tightness around my chest and head. It NEVER goes away. When it started nine months ago, it was mild. I has increased in severity until now, when it is almost unbearable.

I have been on antipsychotics for a year and I wonder if they are the culprit as they can cause muscle stiffness. I do not experience stiffness anywhere else in my body.

Sounds like you're having symptoms of anxiety.
Symptoms of conversion disorder or numbness, Paralysis, etc...

Does it feel like you are unable to get a breath in ?
