Eye bags and puffiness
Tired-looking eyes could be a red flag for chronic allergies, which dilate blood vessels and cause them to leak. In the sensitive skin under your eyes, this creates puffiness and a dark purple-blue hue, says Dr. Raj, who is also co-founder of the skin care company TULA.
This can be one of the first signs of stroke, says Leana Wen, MD, an emergency physician at George Washington University and coauthor of When Doctors Don’t Listen: How to Avoid Misdiagnoses and Unnecessary Tests. “Patients will often describe it like this: ‘I looked in the mirror, and my face looked different.’” You might also notice that one side of your face is numb or feel as if you can’t fully smile. Or you might have trouble speaking. If you suspect that you or a relative may have had a stroke, call 911 right away.
