hi molly,
i had the bladder problem a few months ago and it was from the trazadone i was on. i do not know what meds you are taking, but since our meds often 'numb' our sensation, we can lose the sensation telling us that we 'need to go'. i had been on the trazadone for a while too so it may not be a new med. hope this helps.
fondly, joan
