Sorry to hear that maildude.
My friend and his girlfriend got covid-19 twice in a 4 month period, both times he got it from his girlfriend. He rarely went out, he works from home, but his girlfriend had to go out to an office to work and to go shopping, she probably got covid at a store.
The first time back in March he had burning lungs for about 6 weeks, he didn't go to a hospital or get tested. He had burning lungs and a sore throat and a bit of fatigue. His girlfriend had about a week of fatigue and then she got better. It took him over a week of googling to figure out his own therapy. He didn't lay down, he sat or stood most of the day and did deep breathing to get more oxygen and clear his lungs. He lifted his arms above his head, breathe in thru nose or mouth, hold for 5~10 seconds then breathe out slowly thru the mouth. He did this about 5~10 times every hour or more often. He also took a teaspoon of cold medicine with menthol & an expectorant every 4 hours to keep his lungs clear, and drank hot tea between meals. He kept up this therapy all day every day for 5 weeks until he had no more severe symptoms, but he had minor pains once or twice a day for about a month.
The second time he got sick in August, his girlfriend only had a sore throat and a bit of a headache for a few days then she got better. As soon as his lungs started burning he started his therapy of deep breathing and cold medicine with menthol & an expectorant. This time he got better in about two weeks. But he's not sure if the second time his quicker recovery was due to starting the therapy right away or if his body had a partial immunity to covid-19, or a combination of both. The second time he also had minor pains in his kidneys for a few weeks.
If you can't breathe in deeply and hold your breath for at least 10 seconds, then you should go to the hospital.
My friend had no problem breathing, it just hurt. He tested his lungs every day, he was able to breathe in deeply and hold his breath for at least 30 seconds, that's why he didn't go to a hospital or get tested, he just self isolated at home for 2 months. His girlfriend stayed home for about a month. They both stayed home an extra 2 weeks after getting better.
They got infected the second time because they believed they were immune and were careless. They didn't social distance, wash hands, or wear masks every time they should have.
The problem with covid is that any one therapy does not work for everyone. If you have any difficulty breathing, or other symptoms, it's better to go to a hospital before your symptoms get worse.
Stay safe, wash or disinfect your hands often and WEAR MASKS !!!!
