Re: Sorry for posting AGAIN but I'm seriously worried!
At 4 years old its normal to have tantrums, its also normal to have aches and pains in his legs...growing pains they call it. When I read your first post and you said that he'd seen the doctor three times I assumed he was an adult until I read the rest of it....you mean you have taken him to see the doctor three times. He is a 4 year old and will pick up various colds and viruses over the years to come while he mixes with other children at school etc. Try not to project your health anxieties onto him.
