My son fell off playground equipment in May, and was told by the doctor that the bruise could take over 6 weeks to go away. There was a huge bump on the left side just above the hip that finally went away. Now the bruise is still there, and uder it, it is very hard. My son goes to the bathroom lots now (#2) like every 1/2 hour, and I m starting to wonder if there is a problem, and if it s the fall that may have caused this. I m getting very concerned, and all my doctor says is it will go away. It s been 4 months now, and it s still there. Should I demand to get him tested?
