[|Human|] My soon to be nine year old son complains of his legs getting tired when we walk and his jaw getting tired when he is eating chewy foods. He had mono at four that escalated over time into double pneumonia the put him in the hospital almost two weeks. Could this be rwlated and what should I do?
[|AI|]  Hi... This i snot related to the mono he got at 4 years of age. This is not related to the double pneumonia either. But you are giving a very significant history in the sense that you are quoting that as the kid is doing a specific motor activity with specific muscle groups he is tiring them out easily. This signifies towards a condition called Transient Myasthenia. It may be due to viral origin too. I suggest you get your son evaluated by a pediatrician. Regards -
