Hi,
are you still suffered from the frequent infections?
Today I felt obliged to come on the internet and try and encourage some people who are having these kinds of persistent bladder symptoms / uti's, because a couple of years ago I really knew this pain.
I had about 5 UTI's in the space of a few months, .. when I got my fifth or so, and the doctor told me that my urine sample had no evidence of infection, that got me wondering - what the hell was going on? I had the constant urge to urinate, could often get burning pain, but I had no infection. Anyway, after visiting a naturopath and doing some reading, I made the following life-style changes which have almost completely eliminated my symptoms.
1: Give up soft-drink, fruit juice, or any other drink that contains sugar. (Even though Cranberry juice is recommended for UTI's, just try giving it up as well).
2: Really try and minimise all sugar intake in your diet. Don't eat any cakes, sweets, chocolate, honey, or even fruits. Eat steamed veges, BROWN RICE, fish etc.
3: Do Kegel exercises (research on the internet if you don't know what these are).
4: Walk every day. Do exercise at least once a week, but the more the better.
5: Urinate and wash yourself BEFORE and AFTER sex. Also, encourage your partner to wash himself before sex. Try showering together.
6: Research herbal teas - I don't know off the top of my head which is good for UTI'S, but herbal teas are a great replacement for sugary drinks. You can even chill the herbal teas if it's hot. My favourites are ginger tea, chamomile, green tea... etc
I did all of these things in 2006, and I still try and maintain this kind of lifestyle even now that my symptoms are much reduced.
It is a bit of a pain to make so many lifestyle changes, but you will not find the answer over the counter. If you re-balance your body naturally, it will heal itself and become stronger.
good luck!
