Athlete's Foot and Jock Itch

I have chronic athlete's foot and jock itch. I have been to a dermatologist and tried prescriptions, but they have not worked. I currently use over the counter Lotramin topical cream and spray for the jock itch, and shoe powder for the athletes foot. These things do not completely rid me of the fungus, but only provide temporary relief. I have had this problem for about 10 years, and I need to get rid of it. I break out in jock itch rashes between my thighs and on my butt. The rashes are like discolored itchy patches of skin. As for the athlete's foot, the skin on my feet is brittle and try and cracks, and my nails are brittle and thick and very discolored. The best remedy I have found so far has been to soak my feet in apple cider vinegar. I tried this for some time and it helped, but I just can't do it everyday; it is so inconvenient. I am hoping to find a homeopathic remedy to cure both of these issues. I have a few ideas of what to take, but want to see what you think. Is there a homeopathic remedy that typically cures both of these fungal infections? Any help is greatly appreciated. Thank you!
