I use to get bladder infections alot, last year while I was in college I got one and didn't have time to go to the doctor in order to get medication. I ended up with a kidney infection and was in the hospital for a few days. As it stands now, I have a weak bladder and have to pee all the time (although i don't know it because I've lost alot of the sensitivity) . In my later years, I could have serious complications with my kidneys as well. Its not bad enough that I have accidents or anything.
Anyhow, I was a fool for not going to the doctor when I realized I had one, and now I'm going to pay for it for years.
I still get them every few months.
