Welcome to health care magic forum.
I have read your concern.
First of all let me advice you not to undergo for Practises such as tongue piercing
,since it is not a healthy treatment option.
I would advice yo to apply Anesthetic
gel on the affected area.
Usually in such cases,Ciprofloxacin
along with analgesics has to be administered.
If possible,get the tongue ring removed.
The tissue hanging could be due to severe inflammation.
Maintain oral hygiene
Swish with lukewarm saline frequently.
Hope this helps.
