An example of this is when i find a bump or sore in my mouth I'll continue to lick it all day until I force my self to stop. I also sometimes when I get a sudden pain with no explanation try to recreate it even though is was really painful ex getting a sudden leg pain try to stretch or bend my leg to see if it will start again. Any info would be really helpful like I have no idea why I do this its not like I enjoy it.
