Nicole and TJ I just saw this and I am so sorry that TJ and you have to be going through this. I am sending prayers that TJ's discomfort eases and that he feels better soon so that Nicole's anxiety can ease as well. I am sure there might be some swelling from the area where they had to enlarge his urethra so that may be causing him the discomfort and the urge to pee. Like with an urinary tract infection you have the urge but there is nothing really coming out. Best wished to your whole family.
