I got diagnosed with Pneumonia after catching the Covid19 virus last April 14, 2021. I've been on medication for weeks and started feeling better. But now, whenever I take a deep breath, I notice some discomfort and a bit of pain in the right side of my chest, near the lower rib cage. I work night shifts and this is starting to worry me because it's impacting my job. Could this still be related to what I went through with Pneumonia, or something else?
