ETA after your SWH:
When you leave out all of the essential and very specific information that you just added afterward in the SWH, you will get responses that reflect that lack of information. There was no way for us to know your daughter had been seen by a doctor. That's why 9 out of the 10 currently existing responses mention getting medical advice from a physician (or physician's office, in one case) in real life as opposed to looking here for answers.
There are people who come here from all walks of life in many different kinds of circumstances. Some ask for medical opinions, and indeed, your first line asks if there is a dermatologist here who might "tell me what this small bump is in the crease of my daughter's nose?"
If you had said in your initial question that your daughter was seen by her doctor and that someone in a dermatologist's office had advised you, then my response would have been to get a second opinion from another dermatologist. I suspect the other responders would likely have done the same.
In the future, if you want specific, useful suggestions, it is best to put the relevant details in the original question but know also that questions of a medical nature are going to get responses that direct you back to health care professionals in your community. Hope you can get your daughter's skin care issue resolved soon.
M.,
Even if anyone here is a dermatologist, she/he wouldn't be able to tell you what the bump is without seeing your daughter.
And as far as any responses go, you might get "could be this….could be that," but that doesn't really help your daughter, does it?
She needs to be seen by a physician to be diagnosed, and if necessary, treated. Do you take her for well checks? You say it's been there for several years….have you ever asked her pediatrician about it? Might be best to start there in case your insurance requires a referral for specialists.
Or, you can call you insurance company and ask if a referral is required, and then find out which dermatologists are in your network. Get the names of a few that are within your network, because your first choice might not be taking new patients or there may not be an appointment available for several months.
Whatever you do, do NOT poke, prod, prick, or try to do an extraction. This is not a do-it-yourself project. Not only could you cause more harm, you may introduce bacteria that could cause an infection. Don't do this.
Get her to a doctor and find out what is really going on and what, if anything needs to be done.
Good luck with this
