Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got a
dental abscess and it has led to lump inside mouth due to pus accumulation in the soft tissues..
Commonly it is a localised infection and does not get into blood stream but at times it can enter blood stream and can cause
septicemia and lead to symptoms like
Fever..
But formation of a lump on the finger is not appearing related to dental abscess and does not seems to be due to entering of blood into blood stream..
So I would suggest you to consult a General Physician and get evaluated fo your finger that can b due to bacterial infection or some other causes..
For dental abscess consult an Oral Physician and get evaluated and a thorough clinical evaluation can be done..
You can be advised treatments like
Root Canal Treatment or Extraction depending upon condition of tooth followed by antibiotics and painkillers..
Hope this information helps..
Thanks and regards.
