Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your symptoms you must have
sore throat & associated
otitis media( infection of middle ear). Swollen lymph node below lower jaw is common after infection such as sore throat .
You could try following remedies too.
1.Saltwater gargle- gargling several times a day with warm salt water can reduce swelling in the throat and loosen mucus, helping to flush out irritants or bacteria.Dissolve half a teaspoon of salt in one cup of water. Just remember to spit the water out after gargling, rather than swallowing.
2.You should also take antibiotic like Augmentin/
azithromycin.
3. Take anti-inflammatory drug like acetaminophen/
ibuprofen. It will help reduce fever & swelling.
4.Take a
liquid diet & take rest
If problem persist, Refer to your ENT specialist
Hope this information helps
