My son is 7yrs old he has been having a lot of pain in the front of his left chin and in the left groin pain to where he keep pushing on it to be able to walk.He ends up not being able to walk for at least 3 days then he is back up again for a week or so but with a limp.We took him for x-rays they did hip ones and kneck ones and also took blood work they told us today they see nothing wrong?What do I do now I know there is something wrong.:confused: Mother of an autistic boy
