Fistula post Surgery

Hi, anyone faced a fistula after surgery? Almost one month after her surgery, she started to drain some CSL for a tiny hole in the scar. We were really scared, but NS then explained us that is something that often happen, but is manageable. She is taken now acetazolamide lo decrease CSF production, glue for skin, sticky strips and pressure bandage.

Synthoms she had:

• Fever.
• Headache when moving.

Thanks for your comments.
