Various types of foot rashes

Foot rashes have various underlying causes that you should be familiar with. There are some foot rashes that only affect the heels or toes while others can develop on the upper or base of the feet.

Always bear in mind that foot rashes that affect the entire foot might be chronic. A doctor should be consulted so that an accurate diagnosis can be given once an individual develops a foot rash.

Allergies

Always bear in mind that allergic contact dermatitis can cause pale pinkish skin or reddish scaly rashes and blisters. The lesions typically have evident borders that are straight or at right angles.

One of the usual causes of allergic contact dermatitis on the feet is no other than sensitivity to chromates which are common components in shoe leather. Other possible causes include exposure to dyes, soap or antibacterial creams that contains neomycin as well as products that contain lanolin, nickel or formaldehyde.

Even poison ivy can trigger dermatitis among those who are highly sensitive to the plant. The treatment usually involves antihistamines or topical steroid medications. The prescription steroids such as prednisone are also given in severe cases.

Athlete’s foot

Foot rashes

Always bear in mind that allergic contact dermatitis can cause pale pinkish skin or reddish scaly rashes and blisters.

Athlete’s foot is triggered by a fungal infection on the foot that spreads from humans and animals. Fitness centers and public locker rooms often harbor this fungus which is highly contagious. Scaly, red patches usually manifest in between the toes or on the soles or upper part of the feet.

The condition can cause a ring-shaped area called tinea pedis. It is managed with over-the-counter antifungal drugs or even prescription creams. Take note that creams which contain lactic acid or urea can be utilized to dissolve the scaly rash so that medication can penetrate the skin while topical lotions contain aluminum chloride that can be dabbed on the area to minimize the swelling.

Infection

Infections can also lead to foot rashes. One example is scabies which is a highly contagious infection caused by mites. Patchy, reddened rashes can develop all over the body but typically evident on the hands and feet.

Scabies are common in daycare centers, hospitals and prisons. Due to sensitivity of the body to the Sarcoptes scabiei bug, the rashes initially appear as small-sized bites with scabs that are quite itchy. There is also a thread-like black line close to the rash which indicates where the mites are burrowing. The medicated lotion recommended by the doctor should be applied all over the body to eliminate any leftover eggs as well as mites.

Chronic foot rashes

Foot rashes can become chronic. There are also medical conditions such as psoriasis that can trigger outbreaks instigated by infection, emotional stress, various medications and foot injuries. The usual lesions appear as reddened, scaly rashes with a silver color on top. In most cases, they are present below the toenails and can be managed with topical steroids
