Itching at the edge of the nail requires careful observation of the skin pattern in the itchy area. If the itching is purely itchy and there is no change in appearance, it may be a limited pruritus and hydrocortisone butyrate cream is recommended for application. If the itchy area is accompanied by significant redness and mild pain, it may be considered as nail fungus, which is caused by the nails irritating the surrounding tissues during the growth process. It is recommended to cut off the edges of the nails and apply erythromycin ointment together with mometasone furoate cream on the red, swollen, itchy and itchy area. If you can see visible blisters on the itchy area, it may be caused by herpes simplex virus infection, so it is recommended to apply topical acyclovir cream or recombinant interferon gel.
