Some parts of out body itch because of many reason they might be •Dry Skin •Bug Bites(bedbug/lice/scabies) •Itchy skin condition •Allergic reaction •Skin Cancer •Warning of a disease (Diabetes/HIVetc) (There are other reasons too like: •Reaction to plants and marine life(poison ivy/other plants you might be allergic to/water/pond) •Nerve Problem) Anyways it ming not be something to be afraid of because sometimes my skin too itches without any reason. It can be that we have a dry skin. But if you want to you can go to a dermatologist. Just remember that it is okay to have some rashes and itches. Stay safe
