Pain under the thumbnail can be caused by a variety of factors, including nail growths, nail deformities, inflammatory or infectious diseases, and external or traumatic factors. One possible cause is paronychia, an infection of the skin of the fingers or toes where the skin folds down to meet the nail. This can be caused by bacteria, yeast, or a fungus. Other symptoms of paronychia include redness, swelling, pain, and pus under the skin. People with diabetes or a weakened immune system are more susceptible to nail infections.

Trauma
There are several potential causes of thumb nail pain, including trauma, infections, and diseases. One common infection that can cause thumb nail pain is paronychia, which is an infection of the skin of the fingers or toes where the skin folds down to meet the nail. Paronychia can be caused by bacteria or yeast, and the skin around the nail may become red, swollen, and painful, with pus collecting under the skin. Most cases of paronychia resolve within a week with treatment.
Another potential cause of thumb nail pain is a fungal nail infection. This can occur when the nail is cracked, broken, or trimmed too closely, allowing fungi to enter. People with diabetes or a weakened immune system are more susceptible to nail infections.
In some cases, thumb nail pain may be caused by nail growths, nail deformities, or inflammatory diseases. It is important to see a doctor if you are experiencing persistent or severe thumb nail pain to rule out any serious underlying conditions.

The skin around the nail may become red, swollen, and painful, and pus may collect under the skin. People with diabetes or a weakened immune system are more susceptible to this kind of infection.
