First Signs of Failing Kidney Transplant?

I had lots of migraines but I hadn't had them before. They were from the high blood pressure. I couldn't run at football despite being quite fit usually. And no matter how much I ran I couldn't breathe. It's because your kidneys produce the red blood cells that carry oxygen around your body for the same reason I'd sometimes fall asleep in random places. Like the other person says, a lack of iron makes you feel cold.

I am going through transplant kidney failure. I have symptoms of being cold all the time, lack of energy, exhausted from the time I get up until I go to bed. My gfr is 10 and I'm trying to hold off going on dialysis. I drink a lot of water. I hope you are on the waiting list for a new kidney. I've been on the waiting list for almost 4 years. They have put me inactive and reactivate several times. Don't give up, I have to remind myself that all the time. Good luck and message me anytime
