Hello,my name is dr Dorina Gurabardhi, many conditions can cause raised bumps to appear on your skin. The most common causes of bumps are harmless and don’t require medical treatment, unless you have discomfort. Here are some of the possible reasons for raised skin bumps: -Acne is the most common skin condition -Allergic eczema is an allergic skin reaction that produces an itchy, red skin rash. The rash may consist of raised, red bumps that ooze, drain, or crust. -Boils are infected hair follicles that look like red, raised bumps on the skin. They can be painful, but they eventually go away once they burst and release fluid. -Molluscum contagiosum are small, flesh-colored bumps with a dimple in the center that often form in all parts of the body. They can arise from skin-to-skin contact with someone affected with them. -Psoriasis is a skin disease that causes scaly, itchy, red patches to form on the skin. It can affect any area of the body. -Seborrheic keratoses are round, rough spots on the surface of the skin. They may be skin-colored, brown, or black. Treatment for raised skin bumps depends on the underlying cause. Most of the common causes of skin bumps are harmless, so you probably won’t need treatment. However, if your skin bumps are bothering you, you might be able to have them removed for cosmetic reasons.In cases where additional medical treatment is required, your can take medications that can help eliminate your skin bumps and the underlying cause. For a bacterial infection, you may need antibiotics. You should see a doctor in case: -skin bumps change or worsen in appearance, or last for a long time -you are in pain or they cause discomfort for many days -you don’t know the cause of the bumps -you suspect you have an infection or skin cancer The doctor will perform a physical examination and inspect the skin bumps. The doctor may also perform a skin biopsy to test if it is necessary. Hope my answer helped you,thanks!
