Question: My 16 month old baby shrugs his right shoulder and keeps his right elbow tucked in while running keeping the arm 90 degree angle. Left arm moves naturally. When he was infant if we pulled him by arms he wouldn extend both of them evenly,he would lean toward right side shortening the move of right arm while the left would have better extension. When he plays he is all ok - equal use of both arms. When he stands he is also ok. But only when runs. We took him to pediatric orthopedic cause we felt a small lump on his right collarbone. We had asked pediatricians about it before and some were claiming probably calcification due to broken clavicle on delivery( we never knew he had broken clavicle on delivery). So we took him to pediatric orthopedic. He did xray and there is no calcification. No signs of breakage. Perfect bone frame. So what could be the lump? Why is he tucking his arm while running? Is it connected?thank you.

Is that node dangerous? What is the reason for the node? And when you say neurological doctor does tha mean there might be something wrong with him neurologically? His development is fine so far except for that.

What is considered under local neurological issues? What kind of tests are performed if you know?
