Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Viral
flu symptoms should not last many weeks. She has rightly started on penicillins for possible secondary bacterial infection.
The lumpy feeling must be because of
cough and tenacious phlegm difficult to cough out.
Do you have
wheezing, fever?
Was there any blood in the sputum coughed out?
Associated
gastritis etc. can mimic your symptoms.
I would suggest following up with your treating physician, getting further tested with Xray chest, sputum exam , hemogram etc. Look for any spasm and secondary complications.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. May I request you to rate your experience here before you close.
Thank you and Good luck!
