Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that rash over her body and
redness of her tongue seems to be most probably due to
allergic reaction to any unknown allergen while can also be due to viral infection..
If there is associated fever then it can be due to viral infection..
I would suggest you to consult a Physician and get evaluated and a thorough clinical evaluation and investigations like
blood test to rule out the cause of the symptoms and treatment can be done accordingly..
She can take Levocetrizine for relieving rashes after consulting a local physician..
As of now you can start gargling with a numbing mouthwash containing Lignocaine to relieve the symptoms.
You can also take a
multivitamin tablet daily..
You can take anti inflammatory painkiller like
Ibuprofen..
Suck ice and do cool water rinses..
Avoid spicy food..
Hope this information helps..
Thanks and regards.
