Hi. I'm a newbie and I'm looking for some support. I've been suffering from breathlessness for 3 weeks now and after a raft of tests, most causes have been ruled out. I'm feeling fed up as I get out of breath just going to the loo and I've been off work all this time. I feel fine when loafing on the sofa and I'd like to go back to work but without knowing what's wrong or how long it will take to get better.
