Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that sensitivity to hot cold and spicy foods inside mouth seems to be due to Apthous
Stomatitis leading to inflammation inside mouth and due to inflammation the mouth has become sensitive and painful..
It can be a side effect of the medication that you have taken for cold while can also be due to infection..
Other causes can be deficiency of iron and
vitamin B12, stress, physical trauma to the tongue, allergies,
acid reflux etc..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis..
Treatment of underlying cause will relieve the symptoms..
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..
Drink plenty of cool water and also maintain a good
oral hygiene..
Avoid stress and take sufficient rest..
Hope this information helps..
Thanks and regards.
