Can you have an infection other than an STD?

It truly depends on your symptoms. One natural alternative medicine approach is to treat the "STI" as a fungal infection and go on a diet that completely eliminates sugar, grains, corn, sugary fruits, dairy (except for sour cream and Greek yogurt), caffeine, and all processed foods for about 2 weeks. According to some sources, this should starve off any type of infection that could be lingering in your body as a result of stress, poor diet habits, environmental toxins, etc. If after a few weeks strictly following this plan your infection persists, it could be "legitimate".
