Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain in case if your daughter is having symptoms of upper and lower
respiratory tract infection and the skin are worsening you need to immediately consult ba Pulmonologist and get her evaluated and he can advise investigations like Blood tests, throat swab culture, chest x Ray, complete blood picture to rule out the exact cause of symptoms and treat accordingly..
She can be advised Antibiotics, anti allergics like Levocetrizine, anti inflammatory painkiller like
Ibuprofen, fever reducer like
Acetaminophen, decongestant like
Phenylephrine and Mucolytics like Ambroxol..
As far as Oral ulcers are concerned they can be due to.the infection itself or side effect of any of the medications..
You can make her Gargle with a numbing mouthwash for Lignocaine, take a
multivitamin tablet daily and also do warm saline gargles..
Give her a soft and bland diet with sufficient fluids..
Hope this information helps..
Thanks and regards.
