I am having intermittent sore throat from last 1.5 month. Sometimes it gets fine, sometimes if I eat sth like curd or a juice, it comes again. In between i had gastrists...which is now fine. I had also consulted 2 doctors and got my ecg and chest xray done a month back which were normal. Cbc was fine with little less lympocytes. I am not able to sleep..very anxious due to corona...and sometimes get a feeling that my chest is tight and feel it while taking a deep breath..what can be the reason? I didnt get a fever as such, in between felt tired due to anxiousness , now again i have sore throat and feels i am having fever, but its not there actually..
