i have been having pain around my right side under my ribs, i have had them on and off for a few years but over the last few month nearly a year now it has been a lot more severe and doesnt pass for very long. I have now been having pain in my back on my left side. i have not been feeling prperly hungry for about 7 months now but i eat anyway, i either eat loads in one day then go to the next with eating hardly anything. i have noticed change in bowel movements (today they have been yellow and this is a first) and the frequency in which i drink and have to go to the toilet is not right and i also dont feel thirsty but i will drink something anyway
