Like you said, it's important that everyone gets tested first, before going and blaming all of their symptoms anxiety.
A lot of health problems can mimic anxiety and vice versa.
I read some of your older posts,and, because you posted in an anxiety forum people suggested what you had was likely to be anixety, however, just to be on the safe side, they told you to go get a scan,
which was the best thing to do.
I hope everything goes ok for you...Sorry you have to go through this...
