Thank you for waiting.
I am very sorry for your symptoms.
I understand your concern.
The symptoms sound like an allergy.
Response to allergen varies from person to person.
The cause may not be apparent always.
It is usually from food.
Environmental factors can be there too.
Other probable can be dermatitis, bite.
You can take benadryl now.
Hydrocortisone cream can be applied.
If the symptoms do not improve, I would advise to consult doctor to have an examination.
I hope this information will be helpful.
If you have any query, please feel free to ask.
Your satisfaction is my goal.
