Itchy bottom for months

I've have been struggling with an itchy anus for awhile now. I think its a fungal infection but i am not sure. Whenever i put medicine on it (Lotrimin etc) it burns like crazy. If anyone can identify this it would really help!

I’m not sure what those red marks/wounds are.
If you put neosporin on it will disinfect the area.
Lotrimin is antifungal and if it burns it means thats not the problem.
Is there a reason the area is chafed ? Tight underwear ? Lots of sport ? Bicycle ? Excessive sweating?
You could apply pure 100% Shea butter , or a tea tree oil cream which has a light antibacterial effect.
Most important wash it 2 x day and keep it extra clean until it’s healed.

Also go to a dermatologist
