Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from
Perianal abscess and the most common cause for it seems to be either infected gland in the area or hair
follicle infection or infection in the skin leading to formation of pus under the skin..
Antibiotics is a correct treatment that is advised to you as it is generally a bacterial infection and along with it you also need to take anti inflammatory painkiller like
Ibuprofen to reduce pain and inflammation..
You can also apply a numbing gel over it to relieve pain..
Do cool compresses over it..
In cse if there is no improvement even after 72 hours you need to consult your physician back and he can also do an
Incision and Drainage and also advise you injectable antibiotics to relieve the infection faster..
Hope this information helps..
Thanks and regards.
