Hi doc, my son is 5 yrs old and has fever going up as high as 39C, and down as normal temp 37. The fever has been going for fifth day today. This morning I checked on his temp, 38C and when he stand up he complained of leg pain and could not walk. Whats wrong? Thanks,Netty
Reclothe most common cause of fever with leg pain is viral myositis. I would like to rule out this condition first. Muscle enzymes like CPK, LDH give a clue. This is a blood test and can be done in the nearest lab. There is no specific management of this condition. I would suggest you to consult a pediatrician for proper evaluation and management accordingly. Regards
