Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms if you have got a tooth extracted then pain after 2 days is not an abnormal finding and if the pain is due to extraction then it will gradually resolve as the healing will proceed considerably..
But in your case if the pain is progressively increased and the area to which the pain is radiating that is lower left jaw, left ear and side of neck it seems that there is some disorder related to the jaw joint known as TEMPOROMANDIBULAR JOINT and such a disorder is known as TEMPOROMANDIBULAR JOINT DISORDER..
I would suggest you to wait for one week so that the healing of the extraction socket takes place so that the exact cause can be ruled out as if pain subsides after healing then it is due to the extraction socket..
In case if still the pain continues then you will have to consult an oral physician and get evaluated and get a full mouth x-ray known as
ORTHOPANTOMOGRAM [OPG] done so that he can evaluate the condition of the jaw joints and make a confirmatory diagnosis..
As of now you can take anti-inflammatory painkillers like
Ibuprofen and
muscle relaxant like Chlorzoxasone for relief..
Hope this information helps..
Thanks and regards..
