I just went through this. I was having an extreme bout of HA and about two weeks ago, I swore I had a bladder infection. I had to go constantly and it was small amounts. I had bladder infections all the time when I was younger so I thought I could diagnose myself. The one difference being it didn't burn or hurt.
But I couldn't believe my ears when I went to the doctor and he said "This is straight urine - nothing wrong here." Of course, I was disappointed it wasn't a bladder infection because if not a bladder infection, what else could it be? Ugh.
Well, I guess it was good old anxiety because it is completely gone now. I'm almost though this particular bout of HA - the only lingering symptom I have is a trembling hand. But I'm optimistically chalking this up to anxiety too and thinking it too will pass. Everything else has!
