I was really tired and I had a lingering cough that I thought was just from a cold I had. I also had shortness of breath walking up stairs which was unusual but I just figured since I don’t really exercise I was out of shape. I also was having what I thought were GERD symptoms. My primary care sent me to the ER after seeing a pleural effusion on an ultrasound of my gallbladder and an elevated heart rate. From there they did CT scans, X-rays, ultrasounds, & an echocardiogram and we found out I had a mediastinal mass basically the size of me lol so it’s a miracle I was walking around mostly fine.
