Welcome & Good evening
Your concern is
1. Pilonidal sinus issue
2. Surgery 1and half year before
3. It's recurrence at same place & very painful
4. You don't want surgery right now
5. You want temporary solution
In this context I want to confirm one thing that is weather the pilonidal sinus has been opened and discharging or it is closed and there is collection inside what we call is abscess.
It can be very painful only when Pilonidal sinus is closed and not discharging.
Next Steps
You must consult surgeon, and can go for Laser abscess treatment.
Health Tips
if the pilonidal sinus is discharging then local care with dressings, antibiotics and analgesic may be used.
Thanks
Regards
