The skin around my eyes (eye lids and the area under them) are purple. This has been noticable for a while now (over a year) but has got progressively worse in the last few weeks. Now, the purple is so dark, I look like I was in a bar fight and got two shiners. What causes this? For some info, I have chronic insomnia and serious allergies, but am also been going through tests for over a year and a half now to try to figure out why I have such bad abdominal issues (they are calling it IBS, but I disagree).
