The pelvic floor muscles span the bottom of the pelvis and support the pelvic organs (bladder and bowel, and uterus (womb) in women). When the pelvic floor muscles contract, they can stop the urinary flow. When they relax, they can allow urinary flow. A pelvic floor dysfunction can create problems with bladder control. 

Both contraction and relaxation as well as coordination of these muscles is necessary for the fine control of urination. When these muscles are too weak,  pee can leak out during coughing , sneezing, jumping etc. When these muscles are too tight, they can cause frequent urge to urinate, leaking with strong urge to urinate, and even UTI like symptoms

Common pelvic floor dysfunction bladder symptoms I treat  in my practice:

1. Leaking pee 
2. Burning/stinging with peeing (in absence of an UTI)
3. Dribbling after peeing 
4. Urgency (peeing more than 8 times in a day or more than 2 times at night)
5. Difficulty holding pee in the bladder
6. Painful bladder 
7. Hesitancy ( difficulty starting urination)
