I can go to the loo and then walk down the street and I will sometimes leak. I don’t think it’s my pelvic floor muscles?
Also if I’ve drunk alcohol I can lose control of my bladder completly.
My GP has always sent me away to do more pelvic floor exercises.
The fact that you can visit the toilet and then still leak means you may have problems fully emptying your bladder.
Rather than jut practising pelvic floor exercises, I would recommend visiting a professional for a physical exam. You should ask them to look for bladder stones or tumors, as well as conditions that affect the nerves.
Are you taking any medication? Sometimes, certain medications can impact the bladder.
