I'm so sorry that you were diagnosed however happy for you that you have answers and now on the way to treatment. Buscopan is an antispasmodic which these types of meds do help with the pain. I am IBS-A however I tend to lean more on the constipation side. I also take an antispasmodic called Symax-SL and it works good for me when I get those sudden spasms.
IBS usually comes with discomfort and even though you treat your spasms, you are not curing your IBS, just helping with the pain. There is no cure for IBS but thats not to say that you will have it forever. Some people do and some don't, as your body changes it
opens the possibility that you could get better or in some cases (unfortunately) worse.
Most of the tests really aren't that bad, but can be a little intimidating. They are necessary in some situations so I would definitely listen to your doctors. If they suggest a certain kind of test, you can come here and get our opinions and experiences with these tests as many of us have gone through many of them.
Did your doc suggest a diet change as well? This will not get rid of your problems entirely but may make a difference on your day to day quality of life. I am on a fiber regimen and I have also changed my diet to take out my "trigger" foods that I have identified using a food diary. This is important because you can start noticing what causes you grief and change accordingly.
I hope this helps a little and I hope you keep posting.
