Balanitis and possible diabetes

Hi all

I've come to this forum for hopefully some common sense and a bit of supporrt.

Let's start with the facts: I'm 34, very overweight and currently suffering from Thrush. Symptoms are that I feel like I need a pee all the time - even 2 minutes after my last pee. The nob of the penis is (some days good some days not) very red and there's a small discharge.

I've been to my GP (or his team) 3 times in 6 weeks and had my urine tested for glucose (Diabetes) and my blood tested - kidneys and prosteate. All came back negative about a month ago. They told me to apply Canesten to my dick which I've been doing but the Thrush ain't going away. Two days ago, another doctor at my surgery suggested circumcision - I have a very (very!) generous amount of foreskin - it can be half an inch longer than the end of my dick when I'm not erect. I'm not keen on circumcision - though I would do it if really necessary. One problem is that even if I retract the foreskin to apply the cream - I can't really stop the foreskin sliding back over the nob to cover it completely. So I'm not sure how much good the Canesten's doing. It does calm things down though.

My wife's checked my nob out too - she sees it has been red and has a discharge so I don't disagree with the Thrush diagnosis.

Could someone talk some sense into me please? Every time I sit here wondering whether to have a coffee or whether I can be bothered to try and have another pee, I convince myself that at around 9 stone overweight, it's Thrush coupled with Type 2 diabetes which hasn't been picked up.

Since January I have had my urine tested for Diabetes around 4 times, I had a blood test for it in January and I bought myself a pin prick meter and none of my readings came back any higher than 5.5 at any time of day. The _only_ thing that worries me is in January I had a pin prick test at my surgery which came back 6.3 but to date that is the only reading I've ever had higher than 5.5 - makes me wonder if her meter was correctly calibrated. From time to time, I get thirsty but I have sinus problems so when my nose is blocked, I breathe more through my mouth and this gives me a dry mouth - I don't need to drink.

I'm very happy to diet - but I'm not going to lose 9 stone overnight so I need a good solution.

If anyone could answer for me:
1) How long does Thrush last?
2) Does anything I've explained make people wonder if I should investigate Diabetes any further?
3) Any other advice very welcome (if constructive).
