Adema can SOMETIMES be linked to kidney-failure or certain types of kidney-disease.
I always hate it when folks like you come on here, ask a question, and someone answers "Go see a doctor!". Duuuuhhhh. I came here for advice, not for someone to tell me to go to the doctor!
However, I'm going to have to say it... Go and see a doctor and see what their impressions are. I would not automatically jump to the renal failure/disease conclusion, as you'll stress yourself. Go see your PCP and tell him/her what's going on.
I wish you the best of luck, my friend.
