Robert,
Once you get paranoid about something your body will create all sorts of symptoms that aren't really there. I have read that TC can cause breat tenderness and guess what? Next day I could swear my nipples felt sore!
The tongue pain may be an ulcer and would most likely point to the fact that you're run down fro freaking out about things. I know the feeling too, you're so highly charged all the time that you tire yourself out, which in turn beings on other worrying symptoms.
Could be kidney stones, but could also be your prostate giving you a bit of jib. I'm not surprised at amoxycillin failing, it;s a broad spectrum anti bio and not particularly useful for pinpoiting specific infections.
I'll bet it's nothing to worry about. Maybe even, it's stress, but certainly doesn't sound like anything serious.
Hi, your urologist is right in suspecting kidney stones. The stone may also be down in the ureter. Get the X-ray and Ultrasound KUB (Kidney, ureter bladder) done. Let me know your reports.
