Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems like there is traumatic injury to the
frenulum of tongue leading to ripping of the mucosa that is appearing hanging and does not seems to be anything serious..
Sore throat seems to be due to
throat infection while tenderness in neck can be due to
swollen lymph nodes secondary to infection..
Nothing to worry, you can start doing warm saline gargles and steam inhalations..
Take anti-inflammatory painkiller like
Ibuprofen for relief from pain and inflammation..
Suck throat lozenges..
In case if the skin tag is also painful you can apply numbing gel containing Lignocaine over it..
In case of no improvement in 3 to 4 days consult an Oral physician and get the skin tag evaluated and for no improvement in throat pain consult an ENT Expert and get evaluated and he can advise antibiotics for relieving infection..
Hope this information helps..
Thanks and regards.
