Constant Buttock Rash

I have had for some time now a rash at the top of my buttocks in the crease. It seems to get more irriated during hot days.

Is this a sweat rash?

Is it a yeast infection?

I have had it for year now and would like to resolve it any help would be great.

Hi,
This could be an allergic reaction, maybe due to the sweat or a fungal infection.Both conditions are known to recur.
Fungi thrive in warm environments where it is moist.You can try applying Miconazole (Miconazole nitrate) Ketoconazole Clotrimazole - marketed as Lotrimin or Lotrimin AF (and Canesten in the UK) on the affected area, twice daily for a week.
If it is associated with itching then you can take oral anti-histamines and apply some eucalyptus oil on the area.
To know the exact diagnosis you can get a skin biopsy done.

Does to lotrimin has a steroid in it?

I tried using lotrimin in the past and it seamed to irritate more I was wandering if it was beacuse of the Steroid.

It seams like I had this same Fungas before while I was living in Baton Rouge, then moved to Michigan and had a doctor prescribe some cream that started with and "L" but the word was much longer. It cured it within a couple of weeks. And went away until I moved to Texas and back in the humidity.

Could it be a yeast infection? Is that possible and does a steroid aggervate a yeast infection?

Thanks
