Brief Answer: bone growth and development Detailed Answer: Hi, From the signs you describe doesn't seem to be something serious. In children this happens during bone growth and development. If the child grows up well and she is otherwise healthy, the moments she complains are too short to be considered for a serious disease. Also if the pain goes away without any medication, is an indicator that the body autoregulates it's own equilibrium. You should worry about the pain if you see something unusual at the skin or the joints : edema round the joints, reddening of the skin, or the joints are hot when you touch them. Also, you should worry if the high temperature is present. Otherwise, nothing to be worried is going to happen. If you have further queries, you are begged to contact me again. Best regards, Dr. Sonila
