<human>: My five year old son is complaining that his left side hurts. He has been crying off an on for about an hour now. He can t stand up straight when he walks. At first I thought maybe his bone was just sore after lying on the floor playing. What could this be?
<bot>: Hi, Welcome to Chat Doctor.It's not very clear from your question which part of the body s left side is hurting in your son. There can be various possibilities with every part of the body. I assume that your talking about the trunk part and the possibilities I can think of is some trauma that would have lead to it most commonly in this age group is an accidental collision with a friend while playing. If there is no skin discoloration in that area and no obvious swelling, then hot fomentation and resting that area is a good enough remedy. If pain worsens or persists then you need to consult a pediatrician for this. Hope your query is cleared. Take care.
