Phani:
Once a fungus is cured, it stays away, at least for a long time. If you are continuing to itch that severely, it is likely that the itch comes from concern over persistent fungus and not from fungus itself. Therefore:
1. Stop worrying. Fungus even when present is superficial and easy to cure.
2. Obtain an anti-tich lotion containing camphor and menthol. Apply it as often as needed for itch, every 5 minutes if needed.
3. Apply a moisturizing lotion at bedtime.
4. Do not scratch, as this perpetuates the problem.
Stay in touch with your physician. You most certainly will get better, with no long-term aftereffects.
Best.
