Been ill since early April. Suffering from right, upper quadrant abdominal pains, stabbing feeling which radiates through to the back. This lasts for 1 hour + and I struggle to sleep on my right side when I m having an episode . Joint pains, mostly in right knee and ankles, although I have had injuries in my right knee and left ankle before. Diarrhoea, nausea and severe fatigue and weakness, headaches occur 1/2 times a day and are usually located on the right. I noticed yesterday that my upper arms were boiling hot, as was my neck - felt similar to fresh sunburn. My doctor has hinted at kidney problems (family history too) but any idea of what this could be? Much appreciated!
