I have pneumonia/ bronchitis and it’s starting to go away but now I’m getting sharp shooting pains every so often in my lung, Should I be concerned?

Cough. The chest pain may be related to muscle strain from coughing. Other causes includes inflammation of the pleura, the lining around the lungs. If you are able to exercise and without fever, your illness is resolving.
A follow up with you physician is recommended. .
