Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that
white spots inside the cheek along with red veiny throat and also having a painful swollen lump under the tongue is an indication of infection..
It seems that you have a viral infection leading to red veiny throat that is an indication of inflamed throat along with sores inside mouth..
Secondly a lump under the tongue can be due to causes like an apthous ulcer, swollen
salivary gland etc..
Consult an oral physician and get evaluated and a thorough clinical evaluation and investigations like throat swab culture, blood tests etc can help in diagnosis and treatment can be done accordingly..
As of now you can start gargling with warm saline solution..
Apply numbing gel containing Lignocaine over the painful lump and even on the spots if they are painful.. Take
Vitamin C supplements..
Avoid spicy and chilled foods..
Sip on plenty of warm water..
Hope this information helps..
Thanks and regards.
