My 3 year old son has suddenly started limping, he has no pain anywhere, he hasn't banged it, I've checked for blisters, splinters, I've checked his toe nails, his knees, ankles, hips there is no sign of anything wrong, just this limp, it seems to get worse if his walkin for awhile. Just wondering if anyone else has ever had anything similar!! Don't no weather I should take him to docs or see if it gets better on its own seein as tho he's not in any pain. Thanx in advance x
