Good Afternoon, For About Four Days Now, I Have Had

good afternoon,

for about four days now, I have had throbbing, stabbing, and consistent pain on the upper left side of my chest. Today it hurts to the point to where I am left with out energy and wish to not speak. I know it would be the best choice to seek medical attention, but I have also had a surgery to drain fluid from the lining of my lung (plural effusion) in April and am thinking this may just be a side affect that I am needing to "get over"

Please advise
