Treatment for onycholysis (nail lifting) usually involves keeping nails as short as possible so that they are unlikely to snag on objects and be pulled off the nail bed. Another strategy is to avoid excessive exposure to water by wearing gloves when doing household chores. Taking medications to treat underlying conditions that might be causing the nail symptoms -- such as psoriasis, thyroid conditions, or infections -- may also be recommended.

Oh, usually it begins to turn black if the finger was smashed. It looks the way my son's thumb often looks but if he's not sucking on it, there might be another reason. I would get it checked with the doctor. Also, watch for other symptoms, if there is a fever or pain along with it, that's an emergency. If there are no finger picking issues, sucking issues and it hasn't been smashed then it may just be one of those odd things that happens. In either case, get it checked. It doesn't look serious right now though, not an emergency room trip if there are no other symptoms I would think.

Thank you. No he doesn't suck his finger he is attached to his pacifier. I'll get it checked Monday. :) he does take an iron supplement for anemia.

My son sucks his thumb like a 24/7 lollipop and at age 7 he has had this sort of thing on and off. Sometimes, his thumbnail looks like it's rotting, sometimes it looks like it's going to fall off. He has seen his regular doctor about this and he says that as long as he is not in pain, it's just a normal consequence for long term thumb sucking. We are reducing his need to suck his thumb gradually but it's going to take some time. Old habits die hard! In your situation it sounds like maybe he smashed his finger in a door or something and it's falling off. That can happen. I would get it checked with your pediatrician to be sure there is no infection setting in or underlying issue. Diabetes, heart conditions and other issues can cause a lack of circulation to the extremeties and are serious. If he is on medication it also could be a contributing factor. I would have to see it to give you more information. :)

I posted a picture :)
