Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems like she had chemical burns in her throat due to gargling with Apple Cedar Vinegar leading to inflammation,swelling and pain.
Ice packing throat will be helpful.
Nothing to worry, consult an Otolaryngologist and get evaluated and after a clinical evaluation he can advise you to take anti-inflammatory painkiller like
Ibuprofen for reducing pain and inflammation.
Gargle with
cold water and also drink plenty of cool water as it will relieve inflammation and
redness.
Take a soft and bland diet.
Avoid hot,spicy,hard and acidic foods for relief..
You can also gargle with a numbing mouthwash containing Lignocaine to get relieved from pain especially during meals.
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
