I Am 50 White Male 230 6ft Have Never Had

I am 50 white male 230 6ft have never had any heath issues. However the past 6 months when I eat no matter what it is I have a pain in my right middle side. When I laugh hard or am in an awkward position the pain is horrible. I went to the Dr they did a check x ray - Good , then a ultra sound on my stomach and it was fine. However they then ordered a CT scan and then called me a said I have non evasive kidney stones. I just do not want this to be a drop dead in 6 moths situation. I think it could be more than that.
