It’s often hard to recognize a toenail infection in the early stages, partially because the symptoms are similar to other conditions. However, treating toenail fungus in the early stages gives you the best chance of recovering your healthy nails. To get prompt treatment, it’s best to see your doctor if you have questions. Here are the symptoms of toenail fungus:  Brittleness Change in nail shape Crumbling of the outside edges of the nail Debris trapped under the nail Loosening or lifting up of the nail Loss of luster and shine on the nail surface Thickening of the nail White or yellow streaks on the side of the nail Toenail fungus requires treatment until it is gone. Otherwise, your toenail may be damaged or may develop a worse infection. If you’ve been treating your toenail with vinegar or other home treatments but don’t see an improvement after a 2 week period, you need to see your doctor. You may need a stronger treatment, such as a prescription anti-fungal cream. This is a sign that your fungal infection is getting worse, rather than better. You need to see your doctor as soon as possible to get proper treatment. You may have another condition that’s causing your symptoms, or you may just need a stronger treatment. Diabetes causes poor circulation in your feet, so you’re more susceptible to infections on your feet. Unfortunately, a simple nail fungus infection can develop into something worse if it’s left untreated. However, your doctor can examine your toenails and make a proper diagnosis so you can receive prompt treatment. If left untreated, your toenail fungus can develop into a bacterial infection or a sore that doesn’t heal. Therefore, it’s best to see your doctor as soon as you suspect you have a fungal infection. If home treatments aren’t working for you, your doctor can offer you a prescription treatment. They can explain all of your treatment options and recommend the best one for you. They’ll likely offer you one of the following treatments:   Oral antifungal drugs can help your body fight off the infection.  Prescription antifungal creams can fight the fungus at the site. You’ll apply it once or twice a day, depending on what your doctor recommends.  Medicated nail polish can be painted on daily to help kill the fungal infection. To use it, you paint on a new coat daily. Once a week, use a cotton swab soaked in alcohol to wipe away all of the built up layers. Repeat this process weekly until the infection is gone. In very rare cases, your doctor may recommend surgery to remove the nail if it’s painful and doesn’t respond to treatment. However, it’s unlikely you’ll need to try this treatment.

Summary:
Consult your doctor if you’re not sure you have toenail fungus. See your doctor if your home treatments don’t work. Seek care immediately if your nail is very thick, discolored or deformed. Check with your doctor if you have diabetes and may have nail fungus. Ask your doctor about stronger treatments.
