It is possible for you to feel and know when the bronchitis is kicking in. When you have a change in your symptoms from the usual that you experience this is called an early warning sign. Some doctors will have you start treatment when you first notice the early warning sign, such as the pain in your right lung. Infections, like bronchitis, can make asthma worse. Getting started on treatment for the bronchitis when you first notice the pain, may keep your asthma from getting severe and uncontrollable.
It is also possible that you are experiencing a lung problem other than bronchitis. Having such pain with every bout of acute bronchitis is rather unusual. A chest x-ray and possibly a high resolution CT scan of your chest may be helpful. A pulmonologist would be the type of specialist to identify if a lung problem other than bronchitis is causing your pain.
I'd strongly recommend you contact your doc at the FIRST sign of worsening lung symptoms & tell him/her what you've posted here.
Also, have you been evaluated for allergies and/or gastric reflux? Either or both conditions can make your asthma worse & optimally controlling these conditions can help improve asthma control.
