LE edema, CKD: if you have edema you may be fluid overloaded.Usually an increase in BUN( urea) which occurs in CKD causes itching but your burning may be a variation. Uric acid(not the same as urea) of 7 is upper limits , the edema is the real issue Call your renal doctor today or go to ER as you may need a water pill / IV to get the fluid off . Check CMP, and U/A as you may be spilling protein due to CKD .
