I have MS. Saw this “rash” on my thighs for the first time in July after sitting pool side with capris on. It was about 90* out. Then a few days ago I was sitting at the park with my kids in 73* with jeans on. So both times the sun did not “touch” my thighs. Got home and went into the bathroom and was shocked by the way my thighs looked. Weird that it occured on skin NOT exposed to the sun. The red lines have the appearance of the blood routing through the blood vessels of my thighs. But is only on my thighs and they were not bare to the sun.
Any one know what this is?
Please excuse the hair. It was obviously time to shave
