Hi, I am able to do exercise like skipping, running, jogging, climb stairs atleast 4 floors without breathlessness, i dont know have any problem. But when i speak in lying down position on bed specially in phone, i get heaviness/pressure in chest and mild pain feeling in chest. I did xray, ctscan, ecg and 2d echo. All are normal. I also done Spirometry and Spirometry was also normal. Please help why i feel heaviness in chest while speaking in lye down position. Please help Thanks
