Myalgia after viral fever

My 4 1/2 yr old son had 4 days of fevers above 39 with no other apparent symptoms/cause. After that passed he could not walk for 2 days. I took him to 2 different GPs and 1 Paediatrician. They all confirmed it was viral and not bacterial. The Paed said it is Myalgia and would pass in 48 hours. It is now a week later and he is still limping especially in the mornings. His carves are sore to the touch but not red or hot. It seems more pronounced on the right leg. His joints and hips, strength and nerves have all been checked and are fine. Urine test was fine. Paed says nothing sinister and blood tests are unecessary because we just treat the symptoms. But I am still worried. Did the virus attack the muscles? In which case did it affect the heart? Do we just give painkillers and get lots of rest?
Otherwise he is fine just a juicy cough and clear runny nose.

You have given an excellent description of your son's problem as well as of your concerns. I too am concerned that he has such clear muscle related symptoms and in particular it is important to be sure that he did not have any cardiac involvement especially a condition called myocarditis which is often caused by a virus called coxsackie virus. He needs to be carefully examined and diagnosed by your paediatrician and special muscle and heart related tests must be sent off before one can be sure that he is safely over his recent illness.Please let me know what the results are once he has again been seen by the paediatrician or if you have any further concerns.
