A blister on the tip of your nose. See your doctor immediately, says Draelos. These blisters, often painful, could signal shingles, which is caused by the same virus that causes chicken pox. Though people over 50 and people with a weakened immune system have a higher risk, "anyone who's had chicken pox can get shingles," says Draelos. And shingles on your face can damage an eye, says Draelos, so you must seek treatment.

Heart palpitations accompanied by other symptoms. Your job is stressing you out. Or maybe it's your super active kids. But if you suddenly feel your heart beating extra fast or irregularly, it could signal a cardiac problem—especially if the feeling is accompanied by symptoms like dizziness, chest pain, or shortness of breath. (If you have these latter symptoms, call 911, advises the National Library of Medicine; and call your doctor if you have frequent palpitations or if you have risk factors for heart disease.) "People often think, 'well it's just anxiety,' but there are certain heart conditions that just present that way," Wexler says. So don't assume you can simply wait it out and move on. And, in general, don't think that you're bothering your healthcare provider if you have questions or concerns, says Wexler. If something feels very wrong or if your symptoms are ongoing, make the call.
