I just read your message. Unfortunately, I can offer no information to you, but instead could use some help from you. My 33 year old daughter is pregnant for the first time (approx. 5 months) and has developed this condition. Since you said your's came about during pregnancy can you tell me anything about it? She has no known diseases and her blood work has tested fine. Due to the pregnancy they really don't want to do too much other testing - just telling her it is sometimes pregnancy related. Did yours start during a pregnancy and if so, did it disappear after you delivered. Any help you can give us would be most appreciated. She had one lesion on her shin and now has another on the other shin. Thanks so much and if I unearth any info that might help you I will let you know. Good luck to you.
