Is it normal to have this sensitive of skin?

I have to cut tags off the back of my shirts or they bother me so much and I get a rash at the site where it is rubbing. If I play volleyball my arms sting so much and it seriously hurts and my forearms turn really red. I can never open water bottles or cans of soda myself because it just hurts too much and if I try really really hard and just push through the pain my hand ends up sort of painfully tingling and burning for about 15 minutes after. Not my entire hand, just on the area used to open the bottle, say, the sides of my fingers or center of my palm. I opened a bottle about an hour ago with my palm and I can still feel a slight tingle. I'm trying to think of other examples but these are three things that happened today and I am just curious. Am I a wimp? Or do other people experience this as well?
