A light at the end of the tunnel?

I just hope it's not an oncoming train! lol! I took hubby to a walk-in clinic Saturday evening because he was still complaining of the abdominal/stomach pain, and now it seemed to be in the lower right quadrant also... which made me wonder if it was appendicitis or something related. So off we went... the first clinic we had planned on going to told us there was a 2 hour wait, and we know from experience that they would probably just send him to the ER anyway... so we decided to head towards the hospital. As we got close, I remembered that there is another walk-in clinic in the same building near the hospital where Ev saw the surgeon last week, so we decided to stop there and see if they take his insurance... They do, and there were only 3 people ahead of him in line, so we decided to stop there. I'm so glad we did. The PAC that saw him is one who I have worked with (interpreted for) before in another town... turns out this is her side job on the weekends. She listened to our story and agreed that the appendix should be checked, and also checked him for a inguinal hernia just in case before sending him to the hospital for a CAT scan. Then we went back over to the clinic for the results... appendix is fine, no kidney stones or hernia... then she suggested that the next test that the surgeon would probably recommend would be a special test to see if the gall bladder is functioning. Just because he doesn't have stones doesn't mean that the gall bladder hasn't just quit working altogether. As we talked about his upcoming appointment (not until Thursday) she decided to go ahead and order the test so that they can hopefully get it done and have the results by the time we see the surgeon again, and not have to wait yet another week in agony for it to be done. She also wrote him off of work until Thursday, which is a good thing considering the medication she gave him to try in the meantime is such that he shouldn't be operating any machinery or even driving while taking it. He took his first dose tonight, and was acting really loopy, we'll see tomorrow whether it really makes any difference in the pain.
I feel a lot better after this visit, mainly because she has given us an inkling of what might be going on, and a plan to get to the bottom of it instead of leaving us hanging. (On a side note, I was kind of irked that the surgeon didn't even talk to me after the scope to let me know how it went, and the report the nurses had was scanty at best, and offered no advice for in the meantime.)
I'm hoping that the more things get ruled out, the closer we are getting to finding out what is going on. :)
