Hi ad welcome to HCM
Yes, spleen is situated there but also stomach, left colon and lower part of lungs.
First thing to think about is muscle pulling and it is treated by rest and painkillers.
Some more serious are pneumothorax
and spleen contusion
, and small diaphragmatic rupture but these ones would have more intensive symptoms. Also any kind of pneumonia
can cause such pain. I suggest to wait 3-5 days to see progression of pain. If you have dificulty breathing or any other serious symptom or pain progress go to hospitalas soon as you can.
Wish you good health.
