I have an infected inclusion cyst near front of the neck 1" , 7 days antibiotics did not help. is excision possible with infection, under ga / la?

Incision & drainage: Ruptured cysts can often be treated via an incision and drainage under local anesthesia. If the inflammation has resolved enough, a complete excision is sometimes possible and decreases the chances of recurrence of the cyst. Consult a plastic surgeon or dermatologist for evaluation of treatment options in your case.

Infection: Yes, you may excise the cyst under general anesthesia. Local snesthetic may not be effective because of the change in chemistry caused by the infection.
