I've asked several doctors many questions pertaining to these two problems I've been having, with no luck. Just hoping someone can shed at least a little light on my situation, or at least relating with similar experience. Maybe I'm not alone, ya never know.

So, I've never had any vaginal problems until I was diagnosed with herpes about 9 months ago. Since then I've had 2 UTIs and 2 yeast infections. Not sure they're related, but it just seems kinda weird given that I've had no problems before. I've looked everywhere on the net, asked doctors, but can't find anything. I'm wondering if it's because there's not enough research. Has anyone had anything similar? Like something you are sure is herpes related but couldn't possibly be because there's no proof. I've had just general poor health ever since then (ear infections, constant colds, etc.). Is it possible to have immune problems from herpes? It's type 1 and I've only had one outbreak.
Also, on another note, the second yeast infection was caused by the antibiotics used to treat the second UTI, which has been the worst thing that has ever happened to my vagina. Anyway, I think I have everything mostly under control now, except some mild itching down there. So, I bought some topical benzocaine (Vagisil) to help. It helped, but it also nearly knocked me out. I've had dental work done where I get Novocaine injections and after the epinephrine wears off, I get pretty sedated, "marijuana high" almost. My dentist said this is normal, happens sometimes to some people, and not to worry. I did some research, and the "caine" family comes in esters and amides, benzocaine and Novocaine are esters whereas lidocaine is an amide. I've never (as much as I can remember) had a problem with lidocaine. I'm guessing it's hypersensitivity to esters, but I can't find much information on the subject. It's so bad that I can't use the cream anymore because it makes me so sedated, just by applying it to my vagina.
I'm just pretty generally dissatisfied with my experience as a vagina owner and I'm thinking about getting a refund. Too much maintenance required.
