Hello and welcome to HCM,
The cure of pilonidal sinus/ cyst
is surgical excision.
Conservative treatment will have to used till surgical excision is done.Severe pain
in the sinus can be due to infection of the sinus tract.
A clinical examination to look for the features of infection are required - redness
, tenderness, throbbing sensation, fever
If these symptoms are present, antibiotic therapy will be required before taking the patient for surgery.
Thanks and take care
Dr Shailja P Wahal
