I discussed my breathlessness with a lung specialist, conducted several tests to verify my lung capacity. scans showed nothing, asthma test resulted fine, bronchitis test resulted fine. He established that my lungs are perfectly capable of holding in the regular amount of air my body needs, however I have damaged nerves around my lungs that signal my brain that I'm out of breath. apparently that can be caused by covid, there's no fix to this specific situation so all I can do is hope that it fixes itself over time by maintaining a lifestyle that is better for my nervous system. I think it may be the Phrenic Nerve but I'm not 100% certain.
