after years of dealing with and getting over various chronic pain problems, I have a theory why urinary urgency is the worst of all of them, ....and why my brain has settled on this symptom to perpetuate my TMS crisis. because you HAVE to interact with the physical symptom. you can't ignore it because you have to use the bathroom...and in my case I have to decide how often. When it's not bothering me I go every 60-120 minutes (always have). When it IS bothering me I feel like I have to go again immediately after being in the bathroom. So I can't tell when to go again. If I go, there's momentary relief but then the irritation comes back in minutes, starting a new cycle. So I constantly have to choose between the more frequent trips and momentary relief, or letting it build up over an hour to extreme discomfort just on principle or something. with my shoulder pains, it was (for me) basically constant. granted it was hard to ignore, but I wasn't being forced to interact it with it by a) making a decision when to pee and b) creating an ebb and flow to the cycle of the symptom through my own activity (of going at a certain time).
