It is generally not recommended to pick the blisters of blistering type of foot odor. Foot fungus, also known as tinea pedis, is a fungal infectious skin condition that is primarily caused by an infection with the skin fungus tinea pedis. The skin usually develops pimples, blisters, and flaking, and there is a noticeable itching sensation. In the case of blister tinea pedis, picking the blisters will not usually have a therapeutic effect, and will result in damage to the skin barrier, allowing external bacteria to take advantage of the situation, which may lead to localized bacterial infection, redness, swelling and pain, making the condition worse. If you have blister tinea pedis, it is recommended that you go to a regular hospital and follow the doctor’s instructions to use the appropriate treatment plan.
