Hello,
Thanks for the query to H.C.M. Forum.
Throat pain with infection in larynx,
dry cough,
fever,
eruption of rashes ,
All above mentioned symptoms are suggestive of allergic
bronchitis with super added infection.
Due to this infection there was
laryngitis , hence fever.
Rashes appear before use of any antibiotics so chances of
URTICARIA is there.
Rashes present all over body and fades after two three days.
Reappear when antibiotics started for fever, but that was a coincidence.
Reason of urticaria are many but few of them are,
Mite,
dust,
pollen,
hay,
fine powder,
cold,
sudden ride or fall of temperature,
In sect bite.
So please get in blood examination for eiosinophils count ( increases in allergy).
Consult a physician and have a treatment.
Till antihistamine and mild degree
bronchodilator will provide relief.
Hope I have answered your query.
If further any question I will help.
Good luck.
Dr. HET
