The doctor will see if this is a greyish nail. If so, what kind of external medication is effective,
First of all, you can choose qiangze capsule as the medication for onychomycosis, which is especially resistant. The course of treatment is generally 3 ~ 4 months. You can also choose to touch amolofen iodine tincture and seconazole solution, and take oral antifungal drugs for treatment. Try to remove the diseased nail before external application of drugs, otherwise it will not play a role.
For the situation you described, the picture you uploaded is not very clear. If you observe that the skin is light yellow or gray white, it may also appear. There are local symptoms such as thickening of the stent and layered pinholes in the stent layer. For this case, it belongs to greyish nails, and timely medical treatment is required.
This nail has obvious thickening, so we still consider the gray nail. This situation is considered to be caused by fungal infection. It is necessary to wear the nail thin and apply ketoconazole ointment to alleviate it. At the same time, sodium bicarbonate solution can also be used for cleaning.
