Diva was complaining of heel/arch/ankle pain for about 2 weeks. Being Drama Diva, I kind of blew it off. I did look repeatedly at the foot - no redness, no swelling. Last Friday after continuous complaining I took her into pediatrician, who diagnosed torn/strained ligament or tendon (x-ray was negative for fracture, but this particular hospital has not got the brightest radiologists) She's been on crutches since - not in a cast or boot but a brace that I (gently) Ace wrap on her. So tonight, she takes the Ace off and says "ewwww, a fat foot". So now it's seriously swollen up to above the ankle. No bruising but even the sole of her foot is swollen. Foot is warm and sensation is okay. She's still complaining of pain in same area, no improvement. I'm calling pediatrician in the morning but am moderately freaking out. Does this sound like a strain/torn ligament? Would it not be rather bizarre for swelling to occur 3+ weeks after the original injury? Do I just head straight for ortho doctor?
