Welcome to HCM
We understand your concerns
I went through your description. Stuffy nose is after effect of intenal infection like flu
etc. You did not mention what is the basic reason for which you went to physician. Secondly Amoxycillin
is a broad spectrum antibiotic commonly used for infectious conditions like flu. Dosage of amoxycillin is determined by tking so many things into consideration. In your description you did not mention the dosage also.
In any condition, your physician is the best judge of your case and the prescription should be accurate upto some extent. Anti biotics should start working immediately and for full effect it might take some days according to the severity of the symptoms. Again your doctor is the best judge.
Therefore, please consult your doctor once again and tell him these things. Don't delay.
Hope I am able to clear your doubts. Available for further queries.
