Although neither are deadly, they can be unsightly, uncomfortable, painful, and spread to other parts of the body if left untreated. They are both also retractable through mere contact if left untreated. More over, the two diseases have similar characteristics in appearance and very similar symptoms, however there are a few symptoms listed below that will help you differentiate which is which.

Thickening of the nail, pitting, and deformation are characteristics of both Psoriasis and a nail fungus. Although darkening of the nail is a symptom of a nail fungus, yellowing or browning of the nail is a symptom of psoriasis.When the nail detaches from the nail bed it is typically identified as onycholysis, which is essentially a fungal toenail, however this is also found in cases of psoriasis. Distortion of the nail however is only classified in fungal nails. If chalky buildup should occur underneath the nail causing it to lift then this would be identified as a psoriasis symptom. On the other hand if the nails become brittle and dull then this would be classified as a fungal nail. Lastly, pain or tenderness of the nails can be due to psoriasis, while a foul odor emitting from the feet is tied to nail fungus and athlete’s foot.

Although there are many similarities to psoriasis and nail fungus, it can be easier to identify when comparing the differences. If still unsure and are feeling discomfort in anyway, you should definitely seek out professional help for clarification of your case and treatment options.
