So sorry that you are in this awful situation Rustic. Not knowing is always the worst, and our imagination can make things seem worse still. Having said that, I think it would be worth going to see your GP anyway, and ask him to interpret the test results for you, especially since you are still in pain so even if these results are right, there is still an unresolved problem.
If I see my doctor when I'm really anxious about something, I find it helpful to write down beforehand the questions I want to ask, otherwise they go out if my head when I get into the consulting room. It might also be useful to take someone with you, for support and also to hear what the doctor says, as it can be easy to miss information in your anxiety, and it's useful to have someone to talk things over with after the appointment. Plus, when you are worried that it might be bad news, you don't want to be dealing with it alone.
Good luck and lots of
