Dear Mary Ann: Thank you, I don't think GP knows this either. But (I'm so excited) I almost got to talk to my local Neurosurgeon. He is working light hours, but I did leave a message with his nurse. I was in the bath last evening and when I got out, they were turning dark purple and black/blue. I am going to talk to them come what may. Thanks for your concern. Gina 47/7 mos.
