My kid who is 2.3 yrs fell down from bed while sleeping 3 days back . He was hard to console and was crying more than a hour. After he got up in the morning he hesitated to use his upper right side of the body and was showing his neck that he feels pain. We consulted a pediatrician who was available on sunday.He checked and said there was no severe injury and prescribed a pain killer. Only after a day we could see visible reddish marks right below his right side shoulder ( probably collar bone). He seems normal with his activities but doesn't use his right hand most of the times and if we touch he screams. Is it just a sprain or something serious .We could not consult a pediatrician immediately as we are in vacation
