I am 36 ex smoker (smokeless for a year) I have been to ER twice for chest pains, arm pain and upper back pain. I was told once gatritis and second anxiety so I m getting treated for both. I refuse to take the anxiety MEDS bc I don t trust anxiety MEDS. My GP is saying the same thing. I worry and Google symptoms all day to where I get anxiety and feel something else is wrong with me. I now see in my mouth one of my lymph nodes is bigger than the other. I still have upper back pain and today I felt pain in my right armpit! Is this all anxiety?? I work in the ER at a hospital and now I m thinking of quitting because of stress.
