My son is cutting 9 teeth all in the back & i took him to the doctor last Thursday because he had been tugging on his ear well he has a ear infection & i noticed he had a rash so i asked her about that & she said it was probably a virus. Well fast forward to now the rash is still here & has spread to his back & down his arms. He’s not bothered at all, no fevers. No symptoms of anything at all. I’m just wondering if anyone has a clue of what it could be? Its raised like i can feel the little bumps.
