The causes of red bumps on your legs can be a result of several different conditions.
Common conditions that cause red bumps on your legs are insect bites, folliculitis, keratosis pilaris and even reactions to shaving.
Contact dermatitis is another cause of red bumps or rashes on your legs as well.
You could even be allergic to soap or body wash or creams you may use on your legs, which could result in red bumps or rashes on the legs.
The red bumps on your legs could also be psoriasis, hives, vasculitis, stasis dermatitis or eczema also called atopic dermatitis.
Stasis dermatitis occurs when you have poor circulation in your legs, which can lead to skin inflammation and even possible red blotches, sores and swollen ankles.
Vasculitis is a condition that causes inflammation of your blood vessels and can also cause red or purple spots or bumps on your legs.
Hives are itchy, raised welts which can be caused by allergies, insect bites or some other irritants.
Psoriasis can cause thick, red, scaly patches on your legs.
Eczema also called atopic dermatitis can cause dry, red and itchy patches on your legs and some other areas of the body.
Folliculitis is when hair follicles get inflamed, which is often a result of fungal or bacterial infections or ingrown hairs.
Folliculitis can also appear as small red bumps or pimples and sometimes with pus.
And Keratosis Pilaris is a harmless condition that causes small, rough bumps, often on your thighs and upper arms, which can also be red or skin colored and the bumps are a result of buildup of keratin in the hair follicles.
Other possible causes of red bumps on the legs are chickenpox, heat rash and in rare cases skin cancer.
Most cases of red bumps and rashes on legs and other areas of the body are harmless and nothing to worry about but if the red bumps get worse or are painful, swollen or you also have a fever or the red bumps show signs of infection such as having pus, increased redness or pain or they are persistent and spreading you should seek medical attention.
