I had a URI (upper respiratory infection), was put on antibiotics, got better for awhile, but then it all came back with dizziness, shortness of breath, some pain
in my chest
and lungs when
I took a deep breath and some chest pain
, plus I was literally drained, totally exhausted! Scared the heck out me...I went back to the doctor, took xray's, labs and everything checked out just fine! My doctor told me that sometimes the the infection that causes URI or Bronchitits, etc.
