HAVE TESTED POSITIVE. In this situation.

Hello, My name is Moly Roy.I am 30 years old. I Tested positive on 26th April, 2021. My saturation level is 95(Most of the times)-97 (Sometimes) Though I was asymptomatic so I have no such symptoms related covid but there are two major problems or symptoms (whatever you called) and they are Breathing issue and Chest pain. I am having little breathing difficulties compare to normal breathing and little chest pain,back pain. Right now I am in home isolation and taking all the necessary precautions but thing is that I want to know, what test should I do this time to know about the state of my lungs. Otherwise It is impossible for me or anyone to understand about the state of my lungs. I will be grateful if anyone can help me out in this situation. Thanks Regards,
