<s>[INST] My 22yo daughter has pneumonia and mono. I had a cough for the last 4-5 weeks. Cough left this week, but a uti developed and left sided chest pain that began during cough remains. It hurts on inspiration mostly right below level of ribs. I ve also had a decreased appetite. Might this be an enlarged spleen - and I might have mono as well? [/INST] Hellowelcome to ChatDoctorthe cause of your chest pain during inspiration might be due to one of the following reasons(1) PNEUMONITIS i.e. infection of the lung tissue(2) PLEURISY i.e. inflammation of the outer covering of lungs(3) COSTCO Chat Doctor. .as for your second question, well It's HIGHLY UNLIKELY that your symptoms r due to enlarged spleen so rule out that possibility from your mind and relax take care </s>
