7 Possible Forearm Redness Causes
The list below shows results from the use of our quiz by Buoy users who experienced forearm redness. This list does not constitute medical advice and may not accurately represent what you have.
Non-specific forearm rash
A rash is an area of irritated or swollen skin. Often, rashes are unidentifiable and some variation of normal. For example, scratching one's arm causes it to turn red (which is caused by mast cells releasing chemicals into the local area), but that's completely normal.
Top Symptoms: forearm redness
Symptoms that always occur with non-specific forearm rash: forearm redness
Symptoms that never occur with non-specific forearm rash: fever
Urgency: Wait and watch
Allergic contact dermatitis of the arm
Allergic contact dermatitis is a condition in which the skin becomes irritated and inflamed following physical contact with an allergen. Common products known to cause allergic dermatitis include plants, metals, soap, fragrance, and cosmetics.
Top Symptoms: forearm redness, forearm itch, scabbed area of the forearm

Insect bite on the arm

Cellulitis is a bacterial infection of the deep layers of the skin. It can appear anywhere on the body but is most common on the feet, lower legs, and face.
The condition can develop if Staphylococcus bacteria enter broken skin through a cut, scrape, or existing skin infection such as impetigo or eczema.
Most susceptible are those with a weakened immune system, as from corticosteroids or chemotherapy, or with impaired circulation from diabetes or any vascular disease.
Symptoms arise somewhat gradually and include sore, reddened skin.
If not treated, the infection can become severe, form pus, and destroy the tissue around it. In rare cases, the infection can cause blood poisoning or meningitis.
Symptom of severe pain, fever, cold sweats, and fast heartbeat should be seen immediately by a medical provider.
Diagnosis is made through physical examination.
Treatment consists of antibiotics, keeping the wound clean, and sometimes surgery to remove any dead tissue. Cellulitis often recurs, so it is important to treat any underlying conditions and improve the immune system with rest and good nutrition.
Top Symptoms: fever, chills, facial redness, swollen face, face pain
Symptoms that always occur with cellulitis: facial redness, area of skin redness
Urgency: Primary care doctor
Necrotizing fasciitis of the arm
Necrotizing fasciitis is a potentially life threatening skin condition stemming from the infection of a wound or injury. If left untreated, it can spread to body parts surrounding the infection changing the color of the skin and degrading the tissue underneath. This can result in muscle, tissue or limb loss and a severe body-wide response to the infection.
Rarity: Ultra rare
Top Symptoms: nausea, diarrhea, vomiting, fever, chills
Symptoms that always occur with necrotizing fasciitis of the arm: skin changes on arm
Urgency: Hospital emergency room
Eczema (atopic dermatitis)
Eczema (atopic dermatitis) is a non-contagious chronic skin condition that produces an itchy rash. It is caused by a genetic condition that affects the skin's ability to protect itself from bacteria and allergens. The most susceptible are those with a family history of atopic dermatitis, asthma, or hay fever.
Infants will have a dry, scaly, itchy rash on the scalp, forehead, and cheeks. Older children will have the rash in the creases of elbows, knees, and buttocks.
Without treatment, a child may have trouble sleeping due to the intense itching. Constant scratching may cause skin infections.
Eczema cannot be cured, but it can be controlled through prescribed medications, skin care, stress management, and treatment of food allergies. People with eczema often have allergies to milk, nuts, and shellfish. Keeping the skin clean and moisturized helps prevent flares.
Top Symptoms: trouble sleeping, feeling itchy or tingling all over, dry skin, scalp itchiness, flexor surface rash
Symptoms that never occur with eczema (atopic dermatitis): fever
Urgency: Phone call or in-person visit
Allergic reaction to poison ivy/oak/sumac
Plants of the Toxicodendron genus are found throughout the continental United States, and exposure to these plants is a leading cause of contact dermititis, a medical term used to describe irritation and itching of the skin.
Top Symptoms: rash, itchy rash, red rash, skin changes on arm, stinging or burning rash
Symptoms that always occur with allergic reaction to poison ivy/oak/sumac: itchy rash, rash
Symptoms that never occur with allergic reaction to poison ivy/oak/sumac: fever
