The suspicion of the ER physician that you had aspirated the peanut was probably correct and bronchoscopy, unlike the usual negative Chest X-ray, would probably confirm that diagnosis. Most aspirated foreign do not show on X-ray. To answer your question regarding aspiration, yes, aspiration of a wide variety of foreign bodies, can cause pneumonia and/or lung abscess and fever could be one sign of this complication.
I suggest that you contact your primary care doctor to get his/her opinion and that strong consideration be given to bronchoscopy. Mucinex or any other medication is unlikely to clear whatever was aspirated. Also, the longer you wait, the more likely are you to develop lung infection.
As an aside, should you have children or grandchildren it is a good practice to not allow anyone under the age of 7-10 to eat peanuts, any other nuts, or any food of a similar size or shape.
Thank you for taking the time to answer my question.
it will be 3 weeks this coming Saturday since it happen.I have not had fever yet but do have lots if acid reflux and chest tightnessand on and off wheezing that seems to produce milky white mucous from my chest.I lost 7 lbs since.Since I am scared to eat solid food.
last night I ate ravoli and I swear I felt a piece of it lodge d in my throat near my treachea.I still have no fever but as I said milky white mucous from chestabout 1/8 of a teaspon produce yesterday.Allergies? Aspiration ?
Acid reflux? I am going out if my mind.
Could peanut actually be stuck somewhere in the back if my throat causing problems ? How long will it take a aspiration pnemonia to develop?
Did I mention , I am allergic to most antibotics as well.
