Blisters on the feet may be caused by physiological factors, or they may be caused by pathological factors such as tinea pedis or herpes sweating. Usually, general treatment and medication can be used (such as applying compound benzene sulfonic acid ointment, bifonazole cream, etc. as prescribed by the doctor).
1. Physiological factors: blisters appear due to friction on the feet caused by prolonged walking or ill-fitting shoes. Replace the shoes with suitable ones, change the shoes and socks frequently, and keep the feet dry, and the blisters will be absorbed and disappear on their own.
2. Pathological factors:
(1) Tinea pedis: Tinea pedis is a superficial fungal infection caused by dermatophytes invading the skin of the feet, manifesting as foot infection, blisters, breakouts, vesicles and obvious itching. Usually, medication can be used, such as applying compound benzenesulfonic acid ointment and bifonazole cream as prescribed by the doctor to inhibit the growth and reproduction of fungi, relieve inflammation and eliminate blisters.
(2) Sweat blisters: usually caused by the blockage of sweat glands and poor excretion of sweat, can also be manifested as blisters on the feet. Usually you can use medication, apply sodium salicylate ointment or urea ointment as prescribed by the doctor to promote normal keratin differentiation and moisturize the skin to eliminate blisters.
If the patient has blisters on the feet, it is recommended to actively go to the hospital, under the guidance of the doctor to use medication. The medication should follow the doctor’s instructions.
