Nails

*1. Yuk! Recognize this? Your nails look like a pen cushion.

If your nails have little white nicks and gouges—almost like an icy surface that’s been scraped up—those “pits” may be a sign of the skin disease psoriasis. While you probably think of skin rashes and irritation when you think of psoriasis, pitted nails affect between 80% and 90% of patients with the condition, concludes a study from Dermatology Research and Practice. In fact, some people experience nail issues before there’s any sign of a skin problem, the study authors say.

…And they won’t go away.

Even holding your breath won’t make those hiccups disappear. If those hiccups persist for 48 hours or longer, a study from Taiwan reveals it could be a sign of lung or esophageal cancers, or stroke! Your central nervous system controls hiccupping, and brain issues and some types of cancer affect that system.
