Anyone else suffer with really tight chest, shoulders and back? Feels tight constantly although sometimes it's worse than others (often when I'm just sitting in a chair).
I'm 26 and have had numerous heart and lung tests. Other symptoms include racing heart when I stand or do any activity (though not usually at rest), shortness of breath, head, neck presure, vision disturbances etc.
Docs think it's anxiety - anyone suffer with this, could it be muscle tension?
