Why does onychomycosis ache when pressed

In clinical practice, onychomycosis is a common disease caused by fungal infection of the nail plate and undernail tissue. In clinical practice, onychomycosis does not show pain at the beginning, but mild symptoms at the beginning. Patients can see white spots under the nails, or obvious discoloration of the nail surface, and obvious uneven nail performance. But as the disease progresses, fungal infection of onychomycosis continues to progress, and as it affects the underlying tissues more severely, it does show significant pain, especially when squeezed. And if the patient is not properly treated, it may also cause conditions such as bacterial infection, such as patients who can show symptoms like onychia, which can cause severe pain with a single press.
