Hi. I have a history of anxiety disorder. For this normally I take as needed .25-.5 mg Clonazepam. In the last week, I have been having swollen tonsils, and after conculting a doctors (they ruled out strep), I have been prescribed z-pack, which I am taking for 2nd day now. I am also experiencing a lot of anxiety for the last few days. This morning I by myself thought that my tonsillitis and stuffy head, nose and lungs, ears, red eyes are caused by allergies, and I took claratin 12 hours readytabs, which in addition to making me feel better also calmed down my anxiety, however now (14 hours past) the anxiety came back. My question is: can tonsillitis cause anxiety? Can allergies cause anxiety? Can alergies cause tonsillitis?
