As of last week, I was in class when I noticed a slight burning in my bladder and pressure. It got to the point where I had to be excused to use the bathroom, and when I tried to urinate, nothing came out. Along with this feeling of pressure I experienced a strange tingling sensation in my inner thighs that originated from my bladder. I have had this before, and it was cured with Macrobid. When I went to see my urologist he first time, they found sugar and a assortment of other things in my urine, and I had my blood tested. However, this recent trip came up with clean results, but my urologist put me on Macrobid because it helped my similar symptoms in the past. I was prescribed to take two pills a day, and as a precaution I took a pill with it that masked any burning I might have had during urination. Now, the tingling has gone, but I now feel like after I urinate, it feels as if my bladder is inflating. Sitting down results in a feeling of pressure and the need to urinate more frequently. Sitting in the car on my way to school is miserable, as the vibrations intensify the feeling of having to pee. Using the bathroom at my school isn't the best option, seeing how I have only 5 minute passing periods and the bathrooms are very unsanitary. I'm returning to my urologist tomorrow to have it checked again, any advice is accepted! (also, I apologize if this is under the wrong category, I don't use Y!Answers very often.)
