Hello,

Thanks for your query.

Candidiasis is the commonest form of yeast infection seen in humans. It is an opportunistic infection and favors areas such as waist, groin and genitals due to presence of moisture.
However it is not so virulent infection which is known to spread widespread lesion over night.

Since your previous infections responded well to antifungal (Diflucan), your previous conditions are very likely to be a fungal infection, but based on your description – presence of itching behind the ears, chapped lips and rash spreading all over upper body, this condition is more likely an allergic condition (urticaria) with possible yeast infection over the groin.

A direct examination by a dermatologist will confirm the possibility. In the mean time you may try over the counter antihistamines such as benadryl which might improve your symptoms. Topical caladryl lotion may also benefit you.

Yeast infection is most often recurring problem. It is advisable to follow steps to prevent its recurrence. You might find the following modifications useful:
- Drink plenty of water;
- Always try to wipe yourself dry;
- You can also use a powder containing antifungal like diflucan

Hope this answers your query. Let me know if I have missed out on any concerns. Do accept the answer if you do not have any further queries.

Wish you good and speedy recovery.

Take care and Regards
