What are the common causes of a friction bump and how can it be effectively managed?

Friction bumps are commonly caused by repeated rubbing or pressure on the skin. They can be effectively managed by keeping the affected area clean and dry, using protective padding or bandages, and avoiding further friction or pressure on the area. In some cases, over-the-counter creams or ointments can help reduce discomfort and promote healing. If the friction bump is severe or does not improve with home care, it is important to seek medical attention.
