Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of swelling and tingling of lipsalong with irritated palate and tongue along with
hoarseness of voice seems to be due to
allergic reaction only and can be due to any food or medicine or any other unknown allergen..
As the symptoms improved with steroid
Prednisone it further confirm allergic reaction..
As your tongue seems to be irritated it is leading to exaggeration of taste..
I would suggest you to take
Ibuprofen, gargle with a numbing mouthwash to relieve pain and soreness, suck ice and rinse with cold water..
Take multivitamins daily..
Once the allergic testing results are available treatment of the cause can be done accordingly..
If allergic reaction is ruled out avoid exposure to allergen tto prevent recurring episodes..
You can also take anti allergics like
Benadryl to reduce allergy symptoms in case if there is exposure to allergen..
Hope this information helps..
Thanks and regards.
