I had a partial nephrectomy in 2011 to remove a cancerous tumor. Since then I've been battling nerve damage in my right leg. It has taken 2 years to get the correct cocktail of medications that have allowed me to return to work. I've recently been experiencing some issues, 2 days ago my feet and calves were so swollen I had to go to the ER, they did a cardiovascular ultrasound and there was not a blood clot. My dr prescribed a diuretic and it has helped the swelling, but the throbbing sensation hasn't fully gone away. They did blood tests and everything looked good except my liver enzymes were high, AST/SGOT 54
What does this mean, should I be concerned?
