My Feet Started To Swell Last Monday. They Itched And

my feet started to swell last Monday. they itched and were painful . each day they have swelled up more
now I notice they are swelling on my thighs. I have tried to stay off my feet. the swelling is firm and is
getting more painful. I had an unknown blister on the shin area 3 weeks ago I treated it with antibiotic
ointment and nupercanial ointment, it healed but left a circle of white skin. 2 weeks ago I had a shingle
shot, I did have kidney failure during a sevier illness 2years ago
