Thank you for the query.
Yes, the wound is infected for sure. Usually an abscess
is a result of such infection, and the smell also indicates it. Usually when pilonidal cyst
is incised, it gets healed in a few days. If it does not, either the whole abscess was not evacuated or the infection is antibiotics resistant. In such case it is advisable to have soft tissues ultrasound
performed and microbiological culture test to get to know what antibiotic should be ordered.
After acute inflammation healing, you should get scheduled for cyst removal as such abscess can get created again.
Hope this will help.
