No, it is common. In runners is it is called Runner's nipple. It is from the sweat and the rubbing on your T-shirt causing the nipples to chafe. They can even crack and bleed. Put Vaseline petroleum jelly on them after you shower and when you exercise put is on and a bandage over it as well. They will heal up. And then just do the routine of Vaseline after you shower ongoing.
