Hello Doctor, Myself and my family are facing some shortness of breath during last two months. We are otherwise doing fine and our oxygen saturation is always well maintained (above 98). It's not happening everyday but it's not going away also. I am hearing similar experience from my friends and their families as well( located at different cities). Even my six years old kid sometimes complain about the same. What can be the possibile reason for this? Does the ongoing pandemic have any connection to this? Regards, Sandip
