Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itchy and veiny throat, Yellowish tint on roof of mouth, stuffed nose and spots on throat are all indicating towards Viral
throat infection..
As Viral infection tend to resolve gradually as the virus completes its cycle you can start taking supportive treatment to relieve the symptoms like take anti-inflammatory painkiller like
Ibuprofen to relieve inflammation in throat, anti-allergics like Levocetrizine to relieve itching and running nose,decongestant to relieve congestion, warm saline gargles, steam inhalation and use a humidifier in your room..
You can such throat lozenges..
Drink plenty of warm water..
In case of no resolution consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and throat swab culture can help in diagnosis and treatment can be done accordingly..
Hope this information helps..
Thanks and regards.
