Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that you are suffering from Onchomycosis that is
fungal infection of toenail and it is the cause for loss of toenail as well as discharge from the sides of the toe..
As you are having a fungal infection, then applying Neosporin will not help because it can treat bacterial infection and not fungus..
You should consult a General Physician or a
Dermatologist and get evaluated and he can do a clinical examination and also advise you culture of the discharge to confirm for the exact cause of infection as such symptoms can be seen in bacterial infection also..
In case if fungal infection is ruled out as the cause you can be advised to apply anti-fungal ointments or lotions..
You can be advised to take
oral antibiotics like Terbinafine,
Itraconazole,
Fluconazole etc..
You can also be advised to apply medicated nail polishes..
Snakeroot extract and tea tree oil application can also help..
Keep the area clean and dry to prevent spread of infection..
Hope this information helps..
Thanks and regards.
