* NEW JERSEY MAN ASKS IF HE WILL LOSE HIS THUMB?  READ WHY.

"A few years I had a fungus on my toe.  I had it treated,  and now after having a small accident at work where I cut my thumb, I have contracted a sort of a fungus.  Is it related to my preious fungus or due to my accident.  It does not hurt but have swelling.  Will I lose my thumb?"  ( JS, New Jersey)

Hi JS,

After visiting with you in person, you appear to have onychomycosis (also called tinea unguium), a fungal infection of the nail bed, nail matrix, and or the nail plate.  This infection is most commonly caused by Trichophyton rubrum, which invades the nail bed and underside of the nail plate.   This infection commonly infiltrates the toenails more than the fingernails, and the  fungus most commonly spreads due to exposure to moist environments such as wearing occlusive footwear, walking in gym rooms, spas, or  fitness centers, and not allowing drying of the skin.  

In fact, almost 33% of all skin fungal infections and 50% of all nail disease is linked to onychomycosis.   Fungus in the body may indicate a weakened immune system; thus, your doctor should order tests to check for any immunocompromised states.  In diabetics, onychomycosis may indirectly decrease peripheral circulation worsening venous stasis and diabetic foot ulcers.  

Regardless of the cause, onychomycosis is easily diagnosed, and treatments are readily available.  Although you mentioned applying an over the counter, topical agent to your nails, the spread of the fungus from your toes to your thumb likely suggests that the fungus is in your blood and stronger medicines are needed to kill the fungus.  Commonly used antifungals are terbinafine and itraconazole but doctors may prescribe griseofulvin and  ketoconazole based on the individual patient's allergy and past medical history. 

Your homosexual relations lends credence to the possibility of  you having contracted AIDS and a subsequent weakened immune system.  The weakened immune system lacks the ability to kill bacteria, viruses, and fungus that enter or exist in the blood; thus, pathogens are able to freely float from one extremity of the body to another extremity. 

Set up an appointment with a doctor, let the physician check for any immunocompromised states, have a HIV test done, and upon receiving those results, discuss with your physician the appropriate treatment steps, as needed.   

In the meantime, I humbled by your question and trust.  Happy Holidays.

Respectfully,

Dr. Roshin
