When my GFR and Creatine levels appears to be normal. But my body is saying something different. Currently my legs, hands and feet are swelling. My adomin is swelling, I'm going to restroom however it does not feel like I am releasing everything. The pain is my legs are keeping me up at night, it feels like something is crawling on my legs but nothing is there. Then there's the shortness of breath and sometimes sudsy urine. Should I be concern? Or is this some other underline problem i should be concerned about?
