 Hi, I'm Dr. Greg Rao with Central Minnesota Foot & Ankle. In fact, one out of two people over 50 will become infected with toenail fungus. Prescription oral medications are effective in treating this condition, but there is a risk of side effects and some are not able to take these medications. We suggest laser light therapy as it usually kills the fungus in just two treatments and leaves the nail and surrounding healthy tissues intact. The procedure takes about 20 minutes and there's no recovery period, so don't live with ugly toes. Give us a call or visit centralmnfootankle.com.
