My daughter who is 4.5 years old, fell from cot (0.5 m ht) while playing, she cried and slept off, next day she was all fine (running, jumping, walking), the day after that she started limping indicating pain on her right leg, we got X-ray done, no abnormality was observed, doctor told to take rest for 3 days, then after taking rest for 3 days she was back to normal... After 1 week of being normal, when she comes back after playing in the evening, she starts limping, after she sleeps at night and gets up in the morning, she is back to normal till evening when she goes for playing... Can you please advise what is the problem and solution?
