I have been in pain and going to multiple doctors for 6 months now. Every doctor has told me there is no seeable cause. I have pain in discomfort in my stomach, specifically my upper left near my spleen (I had an enlarged spleen) and my lower right side in my pelvis area. Sometimes I can't eat at all and the pain will wake me up in the middle of the night. I have nausea, but also have started to vomit a lot and the other day there was blood in the mix. The main odd thing is unexplained weight gain. I've gained 60 pounds in this 5-6 months. I've recently been sent to a fitness consultant and dietician, but I am not feeling better, despite all medications and everything all the doctors have tried. I'm unsatisfied with the answer of just giving me a fitness consultant and dietitian because it feel like much worse. I am afraid somewhat that I may have some sort of stomach or ovarian cancer. 5 months ago I got an ultrasound and nothing showed, but I am not sold.
