Constant toddler fever

My son is 2 years and 7 months old now, ever since he was 4 months old he gets fever once a month, most of the times with no other symptoms and it goes after 2 to 3 days with the help of panadol, i am worried about his condition, he also has asthma, but when he used to have his crisis it was without fever, i don't know if they are related, but i need more information, i read something about meditarrenaean fever syndrome and i am worried, please help!

Hi,
How is your son? Were you able to have tests done during these fever episodes such as urinalysis or CBC? A very common cause of fever with no associated symptom is from urinary tract infection. If this recurs, it is best that you check with his doctor for proper evaluation. Direct clinical examiantion and further tests may help identify the underlying cause. Take care and do keep us posted.
