Pain in my bladder when I closed my legs?

Not normal. Unless you had an injury to explain you r symptom, this is obviously not normal, especially if it is new for you. I am not certain what is causing your pain but urinary retention, bladder infection, or a mass pushing on your bladder can do that. I would suggest getting it checked by your doc as soon as it is feasible. Good luck.
Rentention. Get checked...Is your bladder full, do you have an infection...This is an abnormal way to feel.
