It can be really hard to tell sometimes what is what. For me if my symptoms keep going on after a few days it starts sending up red flags for me. I used to just go in and get a blood test, and my sed rate would be quite high. Which was nice because that would let me know I was flaring. However I never knew how bad off I really was until I had my scope on Monday. I was shocked when they said my whole colon/TI was full of scattered ulcers and inflammation. It was quite the wake up call for me, because I always thought my disease was probably more mild and that I was probably controlling it with my rounds of prednisone. So my theories have been all but thrown out the window there!
Most of my flares have all been different too, so that also doesn't help. Some are just diarrhea and cramping. Some come with extreme tiredness, joint pain, vomiting, and erythma nodosum. I've had my lip swell one time. Just pretty much all over the map! So just because I get some symptoms and not others doesn't mean I'm not flaring I've found.
But yes, if it's not just a few days and things seem to be getting worse then better I tend to start looking at getting in touch with the doctors.
