Thanks a bunch for the quick reply.
I do not have any cough or breathlessness. I am just worried about my chest pain. Docotor also did ECG and he said it is normal.
I also have upper back pain (more intense than chest pain) I am not sure if this back pain is radiating around the chest.
Please advise on any home remedies / any tests that I need to get done.
Sometimes for some unlucky people, bronchitis can take up to 2 months to get rid of the dry cough. Your lungs are still healing. Be glad your lung function test results were normal. I had acute bronchitis over 4 months ago ( I also have asthma) and I still now have a wet cough. I bring up mucous from my lungs every day and my lung function is not quite the same anymore. Your chest is probably sore from all of the coughing, which is hard work on the body. Just have patience, it will clear up. As long as you don't have a fever, shortness of breath or coughing up coloured mucous, I think you will be ok.
