“retro”– backwards; “onychia”– nail

caused by ingrowth of the nail plate into the cuticle

common signs are

• redness and swelling of the affected toe at the base of the nail plate
• pus or white fluid on either side of the nail
• little to no new nail growth
• pain when pressing on the toe

DO NOT ignore these signs, it can lead to skin infections

Ways to avoid

• Avoid tight footwear (i.e high heels, narrow tip dress shoes)
• Wear shoes that are the appropriate length for your feet 

Some cases resolve on their own, but if you are unsure, contact a foot clinic to have your toes assessed

Treatments

• antibiotics to treat the infection
• nail removal can be performed at the clinic with local anesthetic, to allow for proper nail growth
