Okay thanks. Does bal tishaktzu apply to those who suffer from frequent urination? It would be aggravating to go to the restroom everytime the urge arises so I hold in until the bladder actually is full or close to full then relieve myself. Then I don’t really suffer much from frequent urination anymore. I usually can distract myself meanwhile and not focus so much on it. It seems doctors do recommend this for bladder training. I also read somewhere that if one can hold for 72 minutes it is also not considered bal tishaktzu. I also read one can delay until they find the proper facilities if it is feasible for tzneuis reasons.
This is a follow up for this: http://dinonline.org/2016/12/22/halachos-for-relieving-outdoors-for-women/
If it is needed for medical reason it is permitted.
