Chest Discomfort. Die of the disease.

Hi, It was around a month ago when I smoked something for the first and only time. I don't know exactly if these symptoms began before or after smoking. I had a sharp pulling kind of feeling of something im the middle of the chest to the right side (about in middle from the nipple and mid).. This feeling occurred when I LAUGHED too hard or coughed too hard. I wouldn't call it painful. It continued for around 10-12 days Then I had a fever and took some medication from local shop for the fever After this the fever and chest discomfort got away. Now after 15 days I feel it's coming back. I am worried if it can be something serious. I am afraid to go to a doctor as there would be many covid patients and I saw some close people around die of the disease.
