Hello all, I hope you can help me with this…I have late stage 4 CKD with an egfr of 18% and am on no medication for anything. I still work full time and have a long train commute. My problem is that most days I feel absolutely fine and can go for a few weeks in good health and with a fair amount of energy yet some days I feel really awful. The symptoms I get are that my hands get cold and ache and my joints ache and I feel so weak and don’t feel like eating or even moving! This lasts for a day or two with me sitting down doing nothing then just as quickly as it came on it is gone and I bounce back to my normal self and feel fine for a couple of weeks. Work are being very good about it (They are fully aware of my kidney problems) but I have had 3 days off in the last fortnight. So my two questions are dear members: a) Is what I have described normal for people with CKD stage 4? b) Is there anything I can do / or take to avoid these episodes?
