Onychomycosis / nail fungus

I have a joke about nail fungus, but it has to grow on you

Lots of people get nail fungus.  It's easy to pick up in the environment just walking around the problem with nail fungus, also called onychomycosis, is that it is very difficult to get rid of.  Your nail beds get very poor blood supply, and fungus is amazingly resilient and tough to kill, so any treatment to help improve it or get rid of it takes a very long time.  If you've ever dealt with dry rot or mold in your house, you know that you have to completely remove anything it's even come close to touching.

For most people, there is no actual harm that comes from having nail fungus.  The only time we see that is either when the amount of fungus under a nail gets so substantial it starts causing pain due to the pressure or sometimes when it creates small breaks in the skin around the nail that lead to a skin infection called cellulitis.  Outside of those two circumstances, treatment is generally purely aesthetic.

Anecdotally, I hear more people apologize for showing me their feet than pictures of their poop.  So I get that we as a society can be sensitive about our feet.  I don't understand why that is, but I get it, exemplified by when my 5 year old told my wife to "wash my nasty nasty feet" when she was in the bathtub.

Let me give you a rundown on the treatments out there:

- Doing nothing.  Research has shown this works 3-5% of the time

- Topical over-the-counter anti-fungal creams like Lotrimin (clotrimazole) or Lamisil (terbinafine).  Used nightly (rubbing under the nails), this works about 10% of the time, if you do it every night for 10-12 months

- Apple cider vinegar and Vicks VapoRub have been shown to have variable efficacy too, probably in line with the topical antifungals, and appear pretty safe to use.

- Prescription topical treatments like Jublia or Penlac work 15-30% of the time, again taking 10-12 months, and while reports vary, I think it can cost $300 a month.

- Oral systemic anti-fungal medications work 30-50% of the time but usually takes about a year to see the results.  Very very rarely, these pills can cause some liver damage as well so we will usually have people do lab work before and sometimes during the course of treatment (typically 3 months of daily pills).

Given that it is generally a benign problem to have, I usually recommend using a topical therapy to improve the appearance of the nails, rather than taking the chance that the oral medicine will work without causing side effects, also knowing that there is a good chance of nail fungus recurring in the future.

Here is some more information for you about how to treat nail fungus without using pills and if you decide to do it, please know you need to be able to stick with it for at least 6 months and in some cases a full year.

Multivitamins

If you can get the lid off, you probably don't need them When I ask people if they are taking any vitamins, herbs or supplements, many people will say they are taking a multivitamin.  When I ask them why they take it, I get a quizzical look most of the time. I think this is something that resonates from childhood and parental advice of the idea that we need vitamins to help our body develop.  I'm not pediatrician so I can't speak to the effects on the developing child, but I will say that most non-pregnant adults without major medical conditions do not need extra vitamins. You'll be impressed by these labels promising 120%, 300%, 1200% of your daily dose of vitamin whatever it is, but the truth is that for most of these vitamins, if you take more than your daily dose your body needs, the rest just ends up in your urine.  You are literally peeing money away in this case. There's been a new trendy vitamin every decade or so for the last 40-50 years; First it...

GERD/Heartburn/Acid Reflux

Let's talk a little about heartburn because it is amazingly common. So what's the problem?  Think of your stomach as being like a soda bottle, which would make your stomach acid the soda (which actually has about the same level of acidity).  That bottle is well designed to deal with the soda in it swishing and swashing the same way your stomach lining has evolved to be very thick so it can handle all the acid. Occasionally, or frequently, you open the bottle and drop something in so it can start dissolving and moving in to your small intestine.  That bottle cap is called the lower esophageal sphincter (LES) and it is an involuntary muscle (so you can't control it) that relaxes and contracts to allow food to come in.  But it also is there to keep stomach acid from splashing up into the esophagus BECAUSE the esophagus does not have the same kind of thick walls the stomach does so it is easily damaged. There are a number of ways that the LES can be interfered w...

Pain

Sorry to be a pain I would say about 90% of the comments I hear from people about their pain threshold is that they think they have a high pain tolerance.  Which is statistically impossible unless I just attract people who have a high pain tolerance. We traditionally ask people to rate their pain on a 1-10/10 scale and while we hear a lot of 9's and 10's, I would say that, having been present for a number of them, a 10/10 would be giving birth to a first child.  For those who haven't experienced that, my old psychiatry resident described it as "so if I lit you on fire and ran you over with my truck, you would not be in any more pain than you are now" (he was also a former Marine sniper which might explain that). But this is pretty pervasive throughout the medical system and got me wondering as to how people's understanding of what their pain threshold was matched up to what it really was.  Fortunately, there were researchers who had a yen to poke peopl...
