Whats wrong with my legs?!?!?

for the past year,when i go to work an stay on my feet for long hours the lower part of my legs an ankles start breaking out into hives,my legs n feet hurt so bad it hurts to walk,and if i sit down for a minute its hard to get back up,it hurts to get up n stand on my feet in the morning when i get out the bed,so i looked online an i found that its physical urticaria.it says to put antihistamine on it or take it,does anyone know what i could do to make it stop appearing because for one its ugly an 2 it burns and im only 23 an it hurts to walk after a while,im not into going to doctors so wanted to try here first..thanks for any advice!
