Sorry about the very delayed reply, everyone. I got pneumonia after covid-flu and got very sick. Covid was no different than the flu (it lasted longer, though), but the pneumonia snuck upon me and got very bad. I thought the shortness of breath was just a lagging symptom of covid and would eventually go away, but it didn't. By the time I went to the doctor, he told me to go to the ER, at which point they immediately hospitalized me because my oxygen reading was so low. They put me on an antibiotic and oxygen, obviously. It took a few weeks to recover after that. I'm about 95% better now, so I've been getting everything in order over the last week. Now I'm back on the boards and will be posting again. Thanks, guys.
