Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that due to
injury there has been traumatic injury to soft tissues leading to tear of mucous and a cut is apparent..
The bump seems to be due to inflammation and
Hematoma formation due to traumatic injury to a small blood vessel leading to spillage of blood into soft tissues..
As the cut is just 1mm Iin size, it needs not to be stitched and will resolve gradually..
You should apply a combination of antibiotic and
steroid ointment over it..
Take anti-inflammatory painkillers like
Ibuprofen..
Do cool compresses over it..l
Avoid touching or scratching it as it can lead to infection and I increased inflammation..
Hope this information helps..
Thanks and regards.
