Use antiseptic gargles and analgesics
Thanks for the query.
You seem to be having inflammation of the throat which is known as pharyngitis
and if tonsil of that side is inflamed then tonsillitis
Inflammation occurs because of infection of the throat and this can result in edema of the lining mucosa of throat. This can give rise to a puffy feeling in the throat and also pain. Reflux can also contribute to this problem.
Please use antiseptic gargles and take proton pump
inhibitor along with an analgesic.
In case the problem does not resolve or increases or fever
appears or the jaw movements become restricted, do see an ENT. If puffiness increases or jaw movements become restricted, there is need to rule out any abscess
formation in that region.
Feel free to ask another query.
