@judimahoney Picking at things including anything on their body is often seen in dementia patients. I have had to use "kerlex", a type of stretchy, sticky bandage that comes on a roll to wrap my husband's arm over the bandage to keep him from taking off the bandage. Labs often use this after taking blood or after you donate blood. I think my husband forgets what is under there and takes it off to investigate. However, moles do change and become cancerous. If it does not heal in a couple of weeks, barring any further picking and bleeding, I would take him to the dermatologist to have the mole evaluated. Good luck!
