Hi, I've been experiencing this uncomfortable feeling in my ribcage and sudden pain just beneath it. I am not satisfied also everytime I breath, seems something blocking the way. When I press my ribs, I feel a little bit relieved. Seems that gas is also present. I've been experiencing this quite a while. Maybe for 4 months now. when I take a deep breath, I cannot really understand what I'm feeling in my abdomen-center. They told me that it's just my mind working, but it's not. I feel anxious about what I feel. I also feel discomfort in my throat. I have done chest xray, KUB ultrasound, t3,t4,tsh and cbc but all negative results. I also feel back pains. Please help.
