Hi and welcome to HCM,
As the extraction was done 2 months back ,normal healing and repair is expected so far. presence of small hole in the extraction area and pain definitly indicates Dry socket
Dry socket is extremely painful condition caused due to dislodgement of blood clot from the extraction socket which exposes the alveolar bone to oral environment and lead to inflammation of the exposed socket bone. It may also lead to super infection if not treated in time .
i suggest you to use a antiseptic mouthwash like chlorhexidine
for mouth rinsing and keep the area clean and moist to prevent infection.
you need to consult a dentist
, who will currette and flush the area to induce fresh blood. Zince oxide eugenol pack is applied as a dressing over the wound and it is replaced every 2 to 3 days till the symptoms subside. till then maintain good oral hygiene
by mouth rinsing and do not hurt the area by brushing or flossing. take care.
