I too developed severe poison ivy/oak and bruising appeared on my inner thighs and lower stomach, the size of large softballs. I am really glad for this site but are we sure this is the reason. My urine became very concentrated and I became very oncerned.I have spent enough time at the drs and hospital so I feel sorta of silly with these repetitions of questions. So if anyone hears of new news, please share. Could solu-medrol cause this or pred?
